1770ae9d3f staging: ks7010: rename return value identifier
Driver uses multiple identifier names for the same task (retval, ret,
rc). It would be easier to read the code if a single task is
identified with a single name. 'ret' is the most common return value
identifier name found in the kernel tree, following the principle of
least surprise using 'ret' is a decent choice.

Rename rc -> ret
Rename retval -> ret

Driver uses different label forms for similar purposes. It would be

Choose label names which say what the goto does or why the goto
exists.

path only exists for the label on an error, prefix the label with

it could not enter the next if-statement. But the "next" if-statement
has the condition to check whether the css_pipe_id equals to
'CSS_PIPE_ID_COPY' or not. It should be removed.

325b5b6c96 staging: bcm2835-audio: Add support for simultanous HDMI and Headphone audio
The firmware for the Raspberry PI already supports simultanous output
of audio through both the HDMI and the Headphone jack.  The current
implementation of ALSA doesn't expose this well to user mode since
the firmware audio is represented as a single card.

A newer approach is taken here and a virtual card is created for each
output(HDMI, Headphones, and Traditional ALSA).  The firmware has
the concept of channels or streams for which the number to use is
passed in the device tree. These streams are allocated to each of the
virtual cards.

As a side effect of this change, since each output is represented
independenly it's now very easy to use PulseAudio to control the
priorities of the outputs.

Testing:

Audacity and VLC were both loaded at the same time.  Each application
was assigned to a different card. With this change I was able to play
different music files at the same time through the HDMI and Headphones
jacks and control the audio independently.

f7d51372d7 bcm2835-v4l2: Fix buffer overflow problem
https://github.com/raspberrypi/linux/issues/1447
port_parameter_get() failed to account for the header
(u32 id and u32 size) in the size before memcpying
the response into the response buffer, so overrunning
the provided buffer by 8 bytes.

Account for those bytes, and also a belt-and-braces
check to ensure we never copy more than *value_size
bytes into value.

ce95e3a9c5 staging: vc04_services: make BCM_VIDEOCORE tristate
Adding the 'bool' symbol brought back a randconfig build bug that
I had fixed before:

drivers/staging/built-in.o: In function `vchiq_probe':
(.text+0x1da30): undefined reference to `rpi_firmware_get'
drivers/staging/built-in.o: In function `vchiq_platform_init':
(.text+0x27494): undefined reference to `rpi_firmware_property'

The problem is that when RASPBERRYPI_FIRMWARE is a loadable module,
but BCM2835_VCHIQ can again be built-in. Making BCM_VIDEOCORE
itself tristate will make Kconfig honor the dependency correctly.

Currently, if pservice is null then service is set to NULL and immediately
afterwards service is dereferenced causing a null pointer dereference. Fix
this by bailing out early of the function with a null return.

media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:174:7: error: dereferencing pointer to incomplete type 'struct acpi_device'

We could work around that in the code, but since we already have a hard
dependency on x86, adding the ACPI dependency seems to be the easiest
solution.

Without CONFIG_PCI, config space reads never return any data,
leading to undefined behavior that gcc warns about:

platform/intel-mid/intel_mid_pcihelpers.c:66:9: error: 'data' is used uninitialized in this function [-Werror=uninitialized]

platform/intel-mid/intel_mid_pcihelpers.c:137:9: error: 'data' is used uninitialized in this function [-Werror=uninitialized]

With a dependency on CONFIG_PCI, we don't get this warning. This seems
safe as PCI config space accessors should always return something
when PCI is enabled.
