2014-06-24xhci: correct burst count field for isoc transfers on 1.0 xhci hostsMathias Nyman
The transfer burst count (TBC) field in xhci 1.0 hosts should be set to the number of bursts needed to transfer all packets in a isoc TD. Supported values are 0-2 (1 to 3 bursts per service interval). Formula for TBC calculation is given in xhci spec section 4.11.2.3: TBC = roundup( Transfer Descriptor Packet Count / Max Burst Size +1 ) - 1 This patch should be applied to stable kernels since 3.0 that contain the commit 5cd43e33b9519143f06f507dd7cbee6b7a621885 "xhci 1.0: Set transfer burst count field."

2014-06-24xhci: Use correct SLOT ID when handling a reset device commandMathias Nyman
Command completion events normally include command completion status, SLOT_ID, and a pointer to the original command. Reset device command completion SLOT_ID may be zero according to xhci specs 4.6.11. VIA controllers set the SLOT_ID to zero, triggering a WARN_ON in the command completion handler. Use the SLOT ID found from the original command instead. This patch should be applied to stable kernels since 3.13 that contain the commit 20e7acb13ff48fbc884d5918c3697c27de63922a "xhci: use completion event's slot id rather than dig it out of command" Cc: stable@vger.kernel.org # 3.13 Reported-by: Saran Neti <sarannmr@gmail.com> Tested-by: Saran Neti <sarannmr@gmail.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-06-24scsi_error: fix invalid setting of host byteUlrich Obergfell
After scsi_try_to_abort_cmd returns, the eh_abort_handler may have already found that the command has completed in the device, causing the host_byte to be nonzero (e.g. it could be DID_ABORT). When this happens, ORing DID_TIME_OUT into the host byte will corrupt the result field and initiate an unwanted command retry. Fix this by using set_host_byte instead, following the model of commit 2082ebc45af9c9c648383b8cde0dc1948eadbf31.

2014-06-23be2net: fix qnq mode detection on VFsSuresh Reddy
The driver (on PF or VF) needs to detect if the function is in qnq mode for a HW hack in be_rx_compl_get() to work. The driver queries this information using the GET_PROFILE_CONFIG cmd (since the commit below can caused this regression.) But this cmd is not available on VFs and so the VFs fail to detect qnq mode. This causes vlan traffic to not work. The fix is to use the the adapter->function_mode value queried via QUERY_FIRMWARE_CONFIG cmd on both PFs and VFs to detect the qnq mode. Also QNQ_MODE was incorrectly named FLEX10_MODE; correcting that too as the fix reads much better with the name change.

2014-06-23rbd: handle parent_overlap on writes correctlyIlya Dryomov
The following check in rbd_img_obj_request_submit() rbd_dev->parent_overlap <= obj_request->img_offset allows the fall through to the non-layered write case even if both parent_overlap and obj_request->img_offset belong to the same RADOS object. This leads to data corruption, because the area to the left of parent_overlap ends up unconditionally zero-filled instead of being populated with parent data. Suppose we want to write 1M to offset 6M of image bar, which is a clone of foo@snap; object_size is 4M, parent_overlap is 5M: rbd_data.<id>.0000000000000001 ---------------------|----------------------|------------ | should be copyup'ed | should be zeroed out | write ... ---------------------|----------------------|------------ 4M 5M 6M parent_overlap obj_request->img_offset 4..5M should be copyup'ed from foo, yet it is zero-filled, just like 5..6M is. Given that the only striping mode kernel client currently supports is chunking (i.e. stripe_unit == object_size, stripe_count == 1), round parent_overlap up to the next object boundary for the purposes of the overlap check.

2014-06-22at86rf230: fix irq setupPhoebe Buckheister
Commit 8eba0eefae24953962067 ("at86rf230: remove irq_type in request_irq") removed the trigger configuration when requesting an irq, and instead relied on the interrupt trigger to be properly configured already. This does not seem to be an assumption that can be safely made, since boards disable all interrupt triggers on boot. On these boards, force the irq to trigger on rising edge, which is also the default for the chip. Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.

It now takes up to 60 seconds to detect cable (un)plug on ADMtek Comet chips. That's too slow and might cause people to think that it doesn't work at all. Poll link status every 2 seconds instead of 60 for ADMtek Comet chips. That should be fast enough while not stressing the system too much. Tested with ADMtek AN983B.

2014-06-22spi: qup: Remove chip select functionAndy Gross
This patch removes the chip select function. Chip select should instead be supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI core assert/deassert the chip select as it sees fit. The chip select control inside the controller is buggy. It is supposed to automatically assert the chip select based on the activity in the controller, but it is buggy and doesn't work at all. So instead we elect to use GPIOs. Signed-off-by: Andy Gross <agross@codeaurora.org> Signed-off-by: Mark Brown <broonie@linaro.org>

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c new drivers from Wolfram Sang: "Here is a pull request from i2c hoping for the "new driver" rule. Originally, I wanted to send this request during the merge window, but code checkers with very recent additions complained, so a few fixups were needed. So, some more time went by and I merged rc1 to get a stable base" So the "new driver" rule is really about drivers that people absolutely need for the kernel to work on new hardware, which is not so much the case for i2c. So I considered not pulling this, but eventually relented. Just for FYI: the whole (and only) point of "new drivers" is not that new drivers cannot regress things (they can, and they have - by triggering badly tested code on machines that never triggered that code before), but because they can bring to life machines that otherwise wouldn't be useful at all without the drivers. So the new driver rule is for essential things that actual consumers would care about, ie devices like networking or disk drivers that matter to normal people (not server people - they run old kernels anyway, so mainlining new drivers is irrelevant for them). * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: sun6-p2wi: fix call to snprintf i2c: rk3x: add NULL entry to the end of_device_id array i2c: sun6i-p2wi: use proper return value in probe i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller support i2c: sunxi: add P2WI DT bindings documentation i2c: rk3x: add driver for Rockchip RK3xxx SoC I2C adapter
2014-06-21net: huawei_cdc_ncm: increase command buffer sizeBjørn Mork
Messages from the modem exceeding 256 bytes cause communication failure. The WDM protocol is strictly "read on demand", meaning that we only poll for unread data after receiving a notification from the modem. Since we have no way to know how much data the modem has to send, we must make sure that the buffer we provide is "big enough". Message truncation does not work. Truncated messages are left unread until the modem has another message to send. Which often won't happen until the userspace application has given up waiting for the final part of the last message, and therefore sends another command. With a proper CDC WDM function there is a descriptor telling us which buffer size the modem uses. But with this vendor specific implementation there is no known way to calculate the exact "big enough" number. It is an unknown property of the modem firmware. Experience has shown that 256 is too small. The discussion of this failure ended up concluding that 512 might be too small as well. So 1024 seems like a reasonable value for now.

In commit 629c9a8fd0bbdfc6d702526b327470166ec39c6b (drivers: net: cpsw: Add default vlan for dual emac case also), api cpsw_add_default_vlan() also changes the port vlan which is required to seperate the ports which results in the following behavior In Dual EMAC mode, when both the Etnernet connected is connected to same switch, it creates a loop in the switch and when a broadcast packet is received it is forwarded to the other port which stalls the whole switch and needs a reset/power cycle to the switch to recover. So intead of using the api, add only the default VLAN entry in dual EMAC case.
