715aa67533 ALSA: snd-meastro3: Ignore spurious HV interrupts during suspend / resume
Ignore spurious HV interrupts during suspend / resume, this avoids
mistaking them for a mute button press. This is not very pretty but
it seems the only way to fix the master volume control gets muted
after suspend issue I'm seeing. Note that the es1968 driver is doing
exactly the same.

7efbfd1ae9 ALSA: snd-meastro3: Add amp_gpio quirk for Compaq EVO N600C
Without this quirk sound stops working after suspend resume. With this quirk,
one still needs to manually unmute the master volume control after a suspend /
/ resume cycle. That is fixed in another patch in this set.

Note that this patch was submitted to the alsa bug tracker a long time ago:

b68b58fd6a ALSA: aaci - Fix alignment faults on ARM Cortex introduced by commit 29a4f2d3
The commit 29a4f2d3 used writel() at offset 0x26 which is
half-word aligned causing unaligned exceptions on a
Cortex-A8. The original patch solved the "aaci-pl041 fpga:04:
ac97 read back fail" issue on a soft reset. Reading from any
arbitrary aaci register seems to solve this issue.

29aac005ff ALSA: usb - Fix Oops after usb-midi disconnection
usb-midi causes sometimes Oops at snd_usbmidi_output_drain() after
disconnection.  This is due to the access to the endpoints which have
been already released at disconnection while the files are still alive.

This patch fixes the problem by checking disconnection state at
snd_usbmidi_output_drain() and by releasing urbs but keeping the
endpoint instances until really all freed.

b0cc58a25d ALSA: mixart: range checking proc file
The original code doesn't take into consideration that the value of
MIXART_BA0_SIZE - pos can be less than zero which would lead to a large
unsigned value for "count".

Also I moved the check that read size is a multiple of 4 bytes below
the code that adjusts "count".

The commit 4d96eb255c broke the interrupt

1c583063a5 ALSA: cmipci: work around invalid PCM pointer
When the CMI8738 FRAME2 register is read, the chip sometimes (probably
when wrapping around) returns an invalid value that would be outside the
programmed DMA buffer. This leads to an inconsistent PCM pointer that is
likely to result in an underrun.

To work around this, read the register multiple times until we get a
valid value; the error state seems to be very short-lived.

f09a15e6e6 USB: Fix usb_fill_int_urb for SuperSpeed devices
USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification.  usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1.  Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.

Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.

Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently.  This allows xHCI roothubs to actually register with khubd.

922a5eadd5 usb: cdc-wdm: Fix race between autosuspend and reading from the device
While an available response is read the device must not
be autosuspended. This requires a flag dedicated to that
purpose.

7f4bca4049 USB: musb: fix warnings in Blackfin regs
The recent commit "usb: musb: Add context save and restore support" added
some stubs for the Blackfin code so things would compile, but it also
added a bunch of warnings due to missing return statements.

adb3ee421d usb: musb: abstract out ULPI_BUSCONTROL register reads/writes
The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY.
However, it has no ULPI support - so there are no registers at all.
That means accesses to ULPI_BUSCONTROL have to be abstracted away
like other MUSB registers.

This fixes building for Blackfin parts again.

9957dd97ec usb: musb: Fix compile error for omaps for musb_hdrc
CONFIG_ARCH_OMAP34XX is now CONFIG_ARCH_OMAP3.

But since drivers/usb/musb/omap2430.c use CONFIG_PM for these
registers and functions, do the same for the header.

Otherwise we get the following for most omap3 defconfigs:

drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'do'
drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'while'
drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'do'
drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'while'
