The dependecies for BACKLIGHT_CLASS_DEVICE are defined a bit
strange, but it seems one has to always select both BACKLIGHT_CLASS_DEVICE
and BACKLIGHT_LCD_SUPPORT to avoid this error:
drivers/gpu/drm/tilcdc/tilcdc_panel.c:396:
undefined reference to `of_find_backlight_by_node'

When GPU acceleration is disabled, drm_vblank_cleanup() will free the
vblank-related data, such as vblank_refcount, vblank_inmodeset, etc.
But we found that drm_vblank_post_modeset() may be called after the
cleanup, which use vblank_refcount and vblank_inmodeset. And this will
cause a kernel panic.
Fix this by return immediately if dev->num_crtcs is zero. This is the
same thing that drm_vblank_pre_modeset() does.
Call trace of a drm_vblank_post_modeset() after drm_vblank_cleanup():

The driver's interrupt handling code is too picky in deciding whether it should
handle an interrupt or not which causes completely unneeded spurious interrupts.
Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read
to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't
get cleared by writing to the SATAINTSTAT register in the interrupt mode we use.
Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for
enabled interrupts and we should clear only those interrupts that we have read
as active first time around, because else we have a race and risk clearing an
interrupt that can occur between read and write of the SATAINTSTAT register
and never registering it...

If enabled, CONFIG_PARPORT_PC_SUPERIO scans on PC-like hardware for
various super-io chips by accessing i/o ports in a range which will
crash any parisc hardware at once.
In addition, parisc has it's own incompatible superio chip
(CONFIG_SUPERIO), so if we disable PARPORT_PC_SUPERIO completely for
parisc we can avoid that people by accident enable the parport_pc
superio option too.

parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus
resources
Supply root bus resources to pci_create_root_bus() so they're correct
immediately. This fixes the problem of "early" and "header" quirks seeing
incorrect root bus resources.
added tests for elmmio_space.start while it should use
elmmio_space.flags. This for example led to incorrect resource
assignments and a non-working stifb framebuffer on most parisc machines.

When a path is gone and dasd_generic_path_event is called with a

handler and the CIO_NO_PATH event, which implies that the subchannel
has been cleared.
If dasd_generic_path_event finds that the path has been the last
usable path, it must not call dasd_generic_last_path_gone (which would
reset the state of running requests), but just set the

====================
Please pull this batch of fixes intended for the 3.10 stream...
Regarding the NFC bits, Samuel says:
"This is the first batch of NFC fixes for 3.10, and it contains:
- 3 fixes for the NFC MEI support:
* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when
moving the LLCP code to the NFC top level directory."
As for the mac80211 bits, Johannes says:
"This time I have a fix from Stanislaw for a stupid mistake I made in the
auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP
and P2P mode fixes for brcmfmac.
Gabor Juhos corrects a register offset for AR9550, avoiding a bus
error.
Dan Carpenter provides a fixup to some dmesg output in the atmel
driver.
And, finally...
Felix Fietkau not only gives us a trio of small AR934x fixes, but
also refactors the ath9k aggregation session start/stop handling
(using the generic mac80211 support) in order to avoid a deadlock.
Please let me know if there are problems!

With the introduction of target_get_sess_cmd() referencing counting for
ISCSI_OP_SCSI_CMD processing with iser-target, iscsit_free_cmd() usage
in traditional iscsi-target driver code now needs to be aware of the
active I/O shutdown case when a remaining se_cmd->cmd_kref reference may
exist after transport_generic_free_cmd() completes, requiring a final
target_put_sess_cmd() to release iscsi_cmd descriptor memory.
This patch changes iscsit_free_cmd() to invoke __iscsit_free_cmd() before
transport_generic_free_cmd() -> target_put_sess_cmd(), and also avoids
aquiring the per-connection queue locks for typical fast-path calls
during normal ISTATE_REMOVE operation.
Also update iscsit_free_cmd() usage throughout iscsi-target to
use the new 'bool shutdown' parameter.
This patch fixes a regression bug introduced during v3.10-rc1 in
commit 3e1c81a95, that was causing the following WARNING to appear:

Go ahead and propigate up the ->cmd_kref put return value from
target_put_sess_cmd() -> transport_release_cmd() -> transport_put_cmd()
-> transport_generic_free_cmd().
This is useful for certain fabrics when determining the active I/O
shutdown case with SCF_ACK_KREF where a final target_put_sess_cmd()
is still required by the caller.

If a key was larger than 64 bytes, as checked by iscsi_check_key(), the
error response packet, generated by iscsi_add_notunderstood_response(),
would still attempt to copy the entire key into the packet, overflowing
the structure on the heap.
Remote preauthentication kernel memory corruption was possible if a
target was configured and listening on the network.

This patch fixes a bug where FILEIO was incorrectly reporting the number
of logical blocks (+ 1) when using non struct block_device export mode.
It changes fd_get_blocks() to follow all other backend ->get_blocks() cases,
and reduces the calculated dev_size by one dev->dev_attrib.block_size
number of bytes, and also fixes initial fd_block_size assignment at
fd_configure_device() time introduced in commit 0fd97ccf4.

During a PCI EEH/AER error recovery flow, if the device did not successfully
restart, the error_detected() hook may be called a second time with a
"perm_failure" state. This patch skips over driver cleanup for the second
invocation of the callback.
Also, Lancer error recovery code is fixed-up to handle these changes.

The following warning was seen on 3.9 when a corrected PCIe error was being
handled by the AER subsystem.
WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90()
This occurred because a call to pci_get_domain_bus_and_slot() was added to
cper_print_pcie() to setup for the call to cper_print_aer(). The warning
showed up because cper_print_pcie() is called in an interrupt context and
pci_get* functions are not supposed to be called in that context.
The solution is to move the cper_print_aer() call out of the interrupt
context and into aer_recover_work_func() to avoid any warnings when calling
pci_get* functions.

c1fdb68e3d73741630ca16695cf9176c233be7ed (USB: EHCI: changes related
to qh_refresh()). The calls to qh_refresh() and qh_link_periodic()
were taken out of qh_schedule(); therefore it is necessary to call
these routines manually after calling qh_schedule().

Passing the value DMA_BIT_MASK(31) to dma_set_mask() causes the
dwc2-pci driver to sometimes fail (cannot enumerate the connected
device). Change it to DMA_BIT_MASK(32) instead, which is a more
sensible value anyway.

regulator_enable_regmap() uses enable_reg to enable the regulator.
But enable_reg for smps10 points to SMPS10_STATUS which is a
read-only register. Fixed the same by having enable_reg
set to SMPS10_CTRL.
