The "Type 2" SMBIOS record that contains Board Name is not
strictly required and may be absent in the SMBIOS on some
platforms.
( Please note that Type 2 is not listed in Table 3 in Sec 6.2
("Required Structures and Data") of the SMBIOS v2.7
Specification. )
Use the Manufacturer Name (aka System Vendor) name.
Print Board Name only when it is present.

Currently when two or more buffers are queued by the camera driver
and so the double buffering is enabled in the idmac, we lose one
frame comming from CSI since the reporting of arrival of the first
frame is deferred by the DMAIC_7_EOF interrupt handler and reporting
of the arrival of the last frame is not done at all. So when requesting
N frames from the image sensor we actually receive N - 1 frames in
user space.
The reason for this behaviour is that the DMAIC_7_EOF interrupt
handler misleadingly assumes that the CUR_BUF flag is pointing to the
buffer used by the IDMAC. Actually it is not the case since the
CUR_BUF flag will be flipped by the FSU when the FSU is sending the
<TASK>_NEW_FRM_RDY signal when new frame data is delivered by the CSI.
When sending this singal, FSU updates the DMA_CUR_BUF and the
DMA_BUFx_RDY flags: the DMA_CUR_BUF is flipped, the DMA_BUFx_RDY
is cleared, indicating that the frame data is beeing written by
the IDMAC to the pointed buffer. DMA_BUFx_RDY is supposed to be
set to the ready state again by the MCU, when it has handled the
received data. DMAIC_7_CUR_BUF flag won't be flipped here by the
IPU, so waiting for this event in the EOF interrupt handler is wrong.
Actually there is no spurious interrupt as described in the comments,
this is the valid DMAIC_7_EOF interrupt indicating reception of the
frame from CSI.
The patch removes code that waits for flipping of the DMAIC_7_CUR_BUF
flag in the DMAIC_7_EOF interrupt handler. As the comment in the
current code denotes, this waiting doesn't help anyway. As a result
of this removal the reporting of the first arrived frame is not
deferred to the time of arrival of the next frame and the drivers
software flag 'ichan->active_buffer' is in sync with DMAIC_7_CUR_BUF
flag, so the reception of all requested frames works.
This has been verified on the hardware which is triggering the
image sensor by the programmable state machine, allowing to
obtain exact number of frames. On this hardware we do not tolerate
losing frames.
This patch also removes resetting the DMA_BUFx_RDY flags of
all channels in ipu_disable_channel() since transfers on other
DMA channels might be triggered by other running tasks and the
buffers should always be ready for data sending or reception.

This reverts commit 47970b1b2aa64464bc0a9543e86361a622ae7c03.
It turns out it breaks several distributions. Looks like the stricter
selinux checks fail due to selinux policies not being set to allow the
access - breaking X, but also lspci.
So while the change was clearly the RightThing(tm) to do in theory, in
practice we have backwards compatibility issues making it not work.

This code makes two calls to clk_get, then test both return values and
fails if either failed.
The problem is that in the first inner if, where the first call to
clk_get has failed, it don't know if the second call has failed as well.
So it don't know whether clk_get should be called on the result of the
second call. Of course, it would be possible to test that value again.
A simpler solution is just to test the result of calling clk_get
directly after each call.
The semantic match that finds this problem is as follows:

Commit 2a48fc0ab242417 ("block: autoconvert trivial BKL users to private

Instrumenting the nbd module's ioctl handler with some extra logging
clearly shows the NBD_DO_IT ioctl being invoked which is a long-lived
ioctl in the sense that it doesn't return until another ioctl asks the
driver to disconnect. However, that other ioctl blocks, waiting for the
module-level mutex that replaced the BKL, and then we're stuck.
This patch removes the module-level mutex altogether. It's clearly
wrong, and as far as I can see, it's entirely unnecessary, since the nbd
driver maintains per-device mutexes, and I don't see anything that would
require a module-level (or kernel-level, for that matter) mutex.

The current TPM TIS driver in git discards the timeout values returned
from the TPM. The check of the response packet needs to consider that
the return_code field is 0 on success and the size of the expected
packet is equivalent to the header size + u32 length indicator for the
TPM_GetCapability() result + 3 timeout indicators of type u32.
I am also adding a sysfs entry 'timeouts' showing the timeouts that are
being used.

This patch fixes an OOPS triggered when calling modprobe ipmi_si a
second time after the first modprobe returned without finding any ipmi
devices. This can happen if you reload the module after having the
first module load fail. The driver was not deregistering from PNP in
that case.
Peter Huewe originally reported this patch and supplied a fix, I have a
different patch based on Linus' suggestion that cleans things up a bit
more.

In zram_read() and zram_write() we were not incrementing the
index number and thus were reading/writing values from/to
incorrect sectors on zram disk, resulting in data corruption.

The ni_tio and ni_tio modules do not depend on the 8255 module, but the
ni_atmio, ni_mio_cs and ni_pcimio modules do need the 8255 module. The
ni_pcimio module also needs the comedi_fc module.

As mentioned by W. Trevor King on the devel@linuxdriverproject.org list
on "Thu, 27 Jan 2011 18:52:15 -0500", "Message-ID:
<20110127235214.GA5107@thialfi.dhcp.drexel.edu>", the ni_pcimio module
is missing module metadata, including a license.
This patch adds module metadata to all the NI comedi driver modules. It
also removes a duplicate MODULE_LICENSE("GPL") line from the "mite"
module.

Commit 93aae17af1172c40c6f74b7294e93a90c3cfaa5d ("sr: implement
sr_check_events()") replaced the media_changed op with the
check_events op in drivers/scsi/sr.c
All users that check for the CDC_MEDIA_CHANGED capbility try both
the check_events op and the media_changed op, but register_cdrom()
was requiring media_changed.
This patch fixes the capability checking.
The cdrom_select_disc ioctl is also using the two operations, so
they should be required for CDC_SELECT_DISC too.

Currently, in case reload pch_can,
pch_can not to be able to catch interrupt.
The cause is bus-master is not set in pch_can.
Thus, add enabling bus-master processing.

Currently, when rmmod pch_can, kernel failure occurs.
The cause is pci_iounmap executed before pch_can_reset.
Thus pci_iounmap moves after pch_can_reset.

Currently, 800k comms fails since prop_seg set zero.
(EG20T PCH CAN register of prop_seg must be set more than 1)
To prevent prop_seg set to zero, change tseg2_min 1 to 2.

Specification links:
- CDC NCM errata link:
http://www.usb.org/developers/devclass_docs/NCM10_012011.zip
- CDC and WMC errata link:
http://www.usb.org/developers/devclass_docs/CDC1.2_WMC1.1_012011.zip
Changes:
- driver updated to match cdc.h header with errata changes
- added support for USB_CDC_SET_NTB_INPUT_SIZE control request with
8 byte length
- fixes to comply with specification: send only control requests supported by
device, set number of datagrams for IN direction, connection speed structure
update, etc.
- packet loss fixed for tx direction; misleading flag renamed.
- adjusted hard_mtu value.

The outvq needs to be woken up on host notifications so that buffers
consumed by the host can be reclaimed, outvq freed, and application
writes may proceed again.
The need for this is now finally noticed when I have qemu patches ready
to use nonblocking IO and flow control.
