Staging: Merge 2.6.37-rc5 into staging-next

2010-12-07T18:47:56+00:00

This was done to handle a number of conflicts in the batman-adv
and winbond drivers properly.  It also now allows us to fix up the sysfs
attributes properly that were not in the .37 release due to them being
only in this tree at the time.

staging: easycap needs smp_lock.h, fixes build error

2010-11-29T18:53:14+00:00

Add header file to fix build error:

drivers/staging/easycap/easycap_main.c:4251: error: implicit declaration of function 'lock_kernel'
drivers/staging/easycap/easycap_main.c:4254: error: implicit declaration of function 'unlock_kernel'

BKL: remove extraneous #include

2010-11-17T16:59:32+00:00

The big kernel lock has been removed from all these files at some point,
leaving only the #include.

Remove this too as a cleanup.

staging/easycap: make module params private/static, fix build

2010-11-16T20:31:49+00:00

The easycap driver has module parameters (bars, gain, & debug)
with global scope that intrude on the kernel namespace and cause
build problems.  Change the names of them to be driver-specific
and make 2 of them static.

drivers/built-in.o:(.bss+0x97c00): multiple definition of `debug'
ld: Warning: size of symbol `debug' changed from 58 in arch/x86/built-in.o to 4 in drivers/built-in.o

staging/easycap: Improve interface to the videodev module

2010-11-10T00:31:16+00:00

The changes here represent an intermediate step towards bringing the
driver within the V4L2 framework.

staging/easycap: Eliminate BKL

2010-11-10T00:31:15+00:00

No locking is required for normal operation of the driver, but locking
is needed to prevent an Oops during some hot-unplugging scenarios.  The
BKL is replaced here by mutex locks together with traps to detect null
pointers following asynchronous device disconnection.

staging/easycap: Avoid compiler warning about frame size ... larger than ...

2010-11-10T00:31:15+00:00

Replacing some of the large automatic variables by dynamically allocated
variables in the IOCTL routines gets rid of the compiler warning.

staging/easycap: Add option to set the hardware audio gain

2010-11-10T00:31:15+00:00

A new module parameter adjusts the gain of the AC'97 audio chip, if
one is present.  Attenuation as well as amplification should be possible
according to the datasheet, but attenuation seems not to work yet.

staging/easycap: Add option to show conspicuous indication of signal loss

2010-11-10T00:31:15+00:00

A new module parameter turns on the option of displaying a testcard when
the analogue input signal is lost (more precisely: when the hardware
detects no field/frame synchronization).  This feature has been requested
in the context of security cameras used at night.

staging/easycap: Implement interlaced modes and reduced framerates

2010-11-10T00:31:15+00:00

Interlaced modes are requested by tvtime.  Reduced framerates are
preferred by some userspace programs, e.g. astronomy applications.
