mn88473: fix chip id check on probe

2017-01-09T07:32:23+00:00

commit d930b5b5bf122a61952cfebabb1e618682a2631a upstream.

A register used to identify chip during probe was overwritten during
firmware download and due to that later probe's for warm chip were
failing. Detect chip from the another register, which is located on
different register bank 2.

gp8psk-fe: add missing MODULE_foo() macros

2016-11-14T16:43:13+00:00

This file was converted to a separate module at commit 7a0786c19d65
("gp8psk: Fix DVB frontend attach"), because the DVB attach routines
require it to work.  However, I forgot to copy the MODULE_foo() macros
from the original module, causing this warning:

    WARNING: modpost: missing MODULE_LICENSE() in drivers/media/dvb-frontends/gp8psk-fe.o

gp8psk: Fix DVB frontend attach

2016-11-13T18:02:22+00:00

The DVB binding schema at the DVB core assumes that the frontend is a
separate driver.  Faling to do that causes OOPS when the module is
removed, as it tries to do a symbol_put_addr on an internal symbol,
causing craches like:

treewide: remove redundant #include

2016-10-11T22:06:33+00:00

Kernel source files need not include  explicitly
because the top Makefile forces to include it with:

  -include $(srctree)/include/linux/kconfig.h

This commit removes explicit includes except the following:

  * arch/s390/include/asm/facilities_src.h
  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

[media] si2165: switch to regmap

2016-09-22T15:56:35+00:00

This avoids some low-level operations.
It has the benefit that now register values van be read from /sys/kernel/debug/regmap
The maximum register value is just a guess - all higher addresses read as zero.
