2015-08-16[media] tc358743: don't use variable length array for I2C writesMauro Carvalho Chehab1-1/+11
drivers/media/i2c/tc358743.c:148:19: warning: Variable length array is used. As the maximum size is 1026, we can't use dynamic var, as it would otherwise spend 1056 bytes of the stack at i2c_wr() function. So, allocate a buffer with the allowed maximum size together with the state var.

This patch adds support for the c8sectpfe input HW found on STiH407/410 SoC's. It currently supports the TS input block, memdma engine and hw PID filtering blocks of the C8SECTPFE subsystem. The driver creates one LinuxDVB adapter, and a demux/dvr/frontend set of devices for each tsin channel which is specificed in the DT. It has been tested with multiple tsin channels tuned, locked, and grabbing TS simultaneously.

2015-08-11[media] stv0367: Refine i2c error trace to include i2c addressPeter Griffin1-4/+8
When using stv0367 demodulator with STi STB platforms, we can have easily have four or more stv0367 demods running in the system at one time. As typically the b2120 reference design ships with a b2004a daughter board, which can accept two dvb NIM cards, and each b2100A NIM has 2x stv0367 demods and 2x NXPs tuner on it. In such circumstances it is useful to print the i2c address on error messages to know which one is failing due to I2C issues.

with pr_warn() On built-in kernels this warning will always splat as this is part of the module init. Fix that by shifting the PAT requirement check out under the code that does the "quasi-probe" for the device. This device driver relies on an existing driver to find its own devices, it looks for that device driver and its own found devices, then uses driver_for_each_device() to try to see if it can probe each of those devices as a frambuffer device with ivtvfb_init_card(). We tuck the PAT requiremenet check then on the ivtvfb_init_card() call making the check at least require an ivtv device present before complaining.
