When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

md_stop() would stop an array, but not free various attached
data structures.
For internal arrays, these are freed later in do_md_stop() or
mddev_put(), but they don't apply for dm-raid arrays.
So get md_stop() to free them, and only all it from dm-raid.
For internal arrays we now call __md_stop.

Commit 952cbaaa9b8beacc425f9aedf370468cbb737a2c (OMAPFB: Change
dssdev->manager references) added checks for OMAPFB_WAITFORVSYNC ioctl
to verify that the display, output and overlay manager exist. However,
the code erroneously uses && for each part, which means that
OMAPFB_WAITFORVSYNC may crash the kernel if no display, output or
manager is associated with the framebuffer.
This patch fixes the issue by using ||.

memcmp->nv_strncmp conversion, in addition to name change, should have
inverted the return value.
But nv_strncmp does not act like strncmp - it does not check for string
terminator, returns true/false instead of -1/0/1 and has different
parameters order.
Let's rename it to nv_memcmp and let it act like memcmp.

Pull libata fixes from Jeff Garzik:
"If you were going to shoot me for not sending these earlier, you would
be right. -rc6 beat me by ~2 hours it seems, and they really should
have gone out long before that.
These have been in libata-dev.git for a day or so (unfortunately
linux-next is on vacation). The main one is #1, with the others being
minor bits. #1 has multiple tested-by, and can be considered a
regression fix IMO.
1) Fix ACPI oops:
https://bugzilla.kernel.org/show_bug.cgi?id=48211
2) Temporary WARN_ONCE() debugging patch for further ACPI debugging.
The code already oopses here, and so this merely gives slightly
better info. Related to
https://bugzilla.kernel.org/show_bug.cgi?id=49151
which has been bisected down to a patch that _exposes_ a latest
bug, but said bisection target does not actually appear to be the
root cause itself.
3) sata_svw: fix longstanding error recovery bug, which was
preventing kdump, by adding missing DMA-start bit check. Core
code was already checking DMA-start, but ancillary, less-used
routines were not. Fixed.
4) sata_highbank: fix minor __init/__devinit warning
5) Fix minor warning, if CONFIG_PM is set, but CONFIG_PM_SLEEP is not
set
6) pata_arasan: proper functioning requires clock setting"

The driver has both SPI and I2C pieces. The appropriate pieces are built based
on whether SPI and/or I2C is/are enabled. However, it was only checking if I2C
was built-in, never if it was built as a module. This patch checks for either
since building both this driver and I2C as modules is possible.

ata_timing_find_mode could return NULL which is not checked by all
low-level ATA drivers using it and cause a NULL ptr deref. Warn at least
so that possible issues can get fixed easily.

The ahci_highbank_probe function is incorrectly marked as __init,
which means it can get discarded at boot time, which might be
a problem if for some reason the device only becomes operational
after loading another module.
Using __devinit instead avoids seeing this warning for every build:
WARNING: vmlinux.o(.data+0xf7b0): Section mismatch in reference from the
variable ahci_highbank_driver to the function .init.text:ahci_highbank_probe()
The variable ahci_highbank_driver references
the function __init ahci_highbank_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
