d11f54b7d1 scsi: lpfc: fix missing spin_unlock on sql_list_lock
From: Colin Ian King <colin.king@canonical.com>

In the case where sglq is null, the current code just returns without
unlocking the spinlock sql_list_lock. Fix this by breaking out of the
while loop and the exit path will then unlock and return NULL as was
the original intention.

332ba3b5d6 scsi: lpfc: don't dereference dma_buf->iocbq before null check
From: Colin Ian King <colin.king@canonical.com>

dma_buf->iocbq is being dereferenced immediately before it is
being null checked, so we have a potential null pointer dereference
bug.  Fix this by only dereferencing it only once we have passed
a null check on the pointer.

b558dfd56a Merge tag 'drm-misc-next-2017-03-06' of git://anongit.freedesktop.org/git/drm-misc into drm-next
First slice of drm-misc-next for 4.12:

Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
  to userspace. I also had the i915 patch in here, but that had a
  small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
  said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
  Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
  Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
  wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
  of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state

Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
  and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
  official, still an experiment, but definitely not complete fail and
  better to avoid confusion. We kinda screwed that up with drm-misc a
  bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over

This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

* tag 'drm-misc-next-2017-03-06' of git://anongit.freedesktop.org/git/drm-misc: (141 commits)

33cc559a81 scsi: lpfc: replace init_timer by setup_timer
This patch shortens every init_timer in lpfc module followed by function
and data assignment using setup_timer.  This is purely cleanup patch, it
does not add new functionality nor remove any existing functionality.

An init_timer call in this form:

    init_timer(&vport->fc_disctmo);
    vport->fc_disctmo.function = lpfc_disc_timeout;
    vport->fc_disctmo.data = vport;

is shortened to:

    setup_timer(&vport->fc_disctmo, lpfc_disc_timeout, vport);

It increases readability and reduces chances of mistakes done by
developers.

bd571195c9 scsi: qedi: fix build error without DEBUG_FS
Without CONFIG_DEBUG_FS, we run into a link error:

drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_poll':
qedi_iscsi.c:(.text.qedi_ep_poll+0x134): undefined reference to `do_not_recover'

qedi_fw.c:(.text.qedi_tmf_work+0x3b4): undefined reference to `do_not_recover'

This defines the symbol as a constant in this case, as there is no way to
set it to anything other than zero without DEBUG_FS. In addition, I'm renaming
it to qedi_do_not_recover in order to put it into a driver specific namespace,
as "do_not_recover" is a really bad name for a kernel-wide global identifier
when it is used only in one driver.

080b47def5 MicroSemi Switchtec management interface driver
Microsemi's "Switchtec" line of PCI switch devices is already well
supported by the kernel with standard PCI switch drivers.  However, the
Switchtec device advertises a special management endpoint with a separate
PCI function address and class code.  This endpoint enables some additional
functionality which includes:

 * Packet and Byte Counters
 * Switch Firmware Upgrades
 * Event and Error logs
 * Querying port link status
 * Custom user firmware commands

Add a switchtec kernel module which provides PCI driver that exposes a char
device.  The char device provides userspace access to this interface
through read, write and (optionally) poll calls.

A userspace tool and library which utilizes this interface is available
at [1].  This tool takes inspiration (and borrows some code) from
nvme-cli [2].  The tool is largely complete at this time but additional
features may be added in the future.

3486935377 ARM: dts: socfpga: Add support for PMU
The dual Cortex-A9 MPCore inside socfpga has a standard PMU unit for
each core mapped in the DAP memory space. Add support for it!

Tested with perf on a Cyclone 5 SoC DK.

439f559109 ARM: dts: socfpga: Do not include skeleton.dtsi
The skeleton.dtsi file is now deprecated as noted in commit 9c0da3cc61
("ARM: dts: explicitly mark skeleton.dtsi as deprecated"). The SoCFPGA
device trees already contain the nodes that are defined in skeleton.dtsi
(#address-cells, #size-cells, chosen, aliases, memory).

Including skeleton.dtsi is useless and will produce the following
warning when compiled with W=1:

Node /memory has a reg or ranges property, but no unit name

cfa6384a01 ARM: dts: socfpga: Remove unit name for LEDs in EBV SOCrates
GPIO LEDs in the Cyclone5 EBV SOCrates board have a unit name but no reg
property. Indeed, GPIO LEDs do not need such a property. They do not
need a unit name neither. This will trigger the following warnings when
compiled with W=1:

Node /gpio-leds/led@0 has a unit name, but no reg property
Node /gpio-leds/led@1 has a unit name, but no reg property
Node /gpio-leds/led@2 has a unit name, but no reg property

The solution is to remove the unit name. In order to have unique node
names, a rename is necessary. This should be harmless as all the LEDs
have a 'label' property, hence their name do not derive from the node
name and will stay the same after this patch.

fbc06b0e10 ARM: dts: socfpga: Remove unneeded reg from stmpe_touchscreen
The stmpe_touchscreen node in Cyclone5 MCV EVK has a reg property, but
this is not used by the driver. Moreover the binding documentation do
not define this property. Having a reg property without a unit name will
trigger the following warning when compiled with W=1:

Node /soc/i2c@ffc04000/stmpe811@41/stmpe_touchscreen has a reg or ranges
property, but no unit name

Remove the superfluous reg property.
