Jingoo Han 1b21ec5a28 leds: leds-lp5523: fix build warnings
This patch fixes build warnings as below:

drivers/leds/leds-lp5523.c: In function 'lp5523_selftest':
drivers/leds/leds-lp5523.c:496:18: warning: 'adc' may be used uninitialized in this function [-Wuninitialized]

drivers/leds/leds-lp5523.c:201:5: note: 'status' was declared here

If lp5523_read() returns an error, problems will happen. Thus,
when lp5523_read() returns an error, it should be handled.

Roland Stigge 04553e925b leds: leds-gpio: Defer probing in case of deferred gpio probing
This patch makes leds-gpio's probe() return -EPROBE_DEFER if any of the gpios
to register are deferred themselves. This makes a change of
gpio_leds_create_of()'s return value necessary: Instead of returning NULL on
error, we now use ERR_PTR() error coding.

Linus Torvalds 35f95d228e Most important part of this is that it fixes a regression in Samsung
NAND chip detection, introduced by some rework which went into 3.7. The
 initial fix wasn't quite complete, so it's in two parts. In fact the
 first part is committed twice (Artem committed his own copy of the same
 patch) and I've merged Artem's tree into mine which already had that fix.
 
 I'd have recommitted that to make it somewhat cleaner, but figured by
 this point in the release cycle it was better to merge *exactly* the
 commits which have been in linux-next.
 
 If I'd recommitted, I'd also omit the sparse warning fix. But it's there,
 and it's harmless — just marking one function as 'static' in onenand code.
 
 This also includes a couple more fixes for stable: an AB-BA deadlock in
 JFFS2, and an invalid range check in slram.

Pull block layer fixes from Jens Axboe:
 "Distilled down version of bug fixes for 3.7.  The patches have been
  well tested.  If you notice that commit dates are from today, it's
  because I pulled less important bits out and shuffled them into the
  3.8 mix.  Apart from that, no changes, base still the same.

  It contains:

   - Fix for aoe, don't run request_fn while it's plugged.

   - Fix for a regression in floppy since 3.6, which causes problems if
     no floppy is found.

   - Stable fix for blk_exec(), don't touch a request after it has been
     sent to the scheduler (and the device as well).

   - Five fixes for various nasties in mtip32xx."

 "Networking bug fixes, Cacio e Pepe edition:

  1) BNX2X accidently accesses chip rev specific registers without an
     appropriate guard, fix from Ariel Elior.

  2) When we removed the routing cache, we set ip_rt_max_size to ~0 just
     to keep reporting a value to userspace via sysfs.  But the ipv4
     IPSEC layer was using this to tune itself which is completely bogus
     to now do.  Fix from Steffen Klassert.

  3) Missing initialization in netfilter ipset code from Jozsef
     Kadlecsik.

  4) Check CTA_TIMEOUT_NAME length properly in netfilter cttimeout code,
     fix from Florian Westphal.

  5) After removing the routing cache, we inadvertantly are caching
     multicast routes that end up looping back locally, we cannot do
     that legitimately any more.  Fix from Julian Anastasov.

  6) Revert a race fix for 8139cp qemu/kvm that doesn't actually work

Guennadi Liakhovetski a7227a0faa PM / QoS: fix wrong error-checking condition
dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.

Another tiny patch.

Removed __packed before the struct smart_attr and added __packed at end of
the structure to fix padding issue.

Ed Cashin 11cfb6ff73 aoe: avoid running request handler on plugged queue
Calling the request handler directly on a plugged queue defeats
the performance improvements provided by the plugging mechanism.
Use the __blk_run_queue function instead of calling the request
handler directly, so that we don't interfere with the block
layer's ability to plug the queue.

Jens Axboe 7c5d62388e mtip32xx: fix shift larger than type warning
If we're building a 32-bit kernel and CONFIG_LBADF isn't set,
sector_t is 32-bits wide. The shifts by 32 and 40 are thus
larger than we support.

Cast the sector offset to a u64 to avoid these warnings.
