      [media] saa7164: silence GCC warnings · b4c13d3d
      由 Paul Bolle 提交于 
      Compiling the saa7164 driver without CONFIG_VIDEO_ADV_DEBUG set triggers
these GCC warnings:
    drivers/media/pci/saa7164/saa7164-encoder.c:1301:12: warning: ‘saa7164_g_register’ defined but not used [-Wunused-function]
    drivers/media/pci/saa7164/saa7164-encoder.c:1314:12: warning: ‘saa7164_s_register’ defined but not used [-Wunused-function]
Silence these warnings by wrapping these two functions in an "#ifdef
CONFIG_VIDEO_ADV_DEBUG" and "#endif" pair.

      [media] imon: fix Knob event interpretation issues on ARM · 24dec5da
      由 Alexandre Lissy 提交于 
      Events for the iMon Knob pad where not correctly interpreted on ARM,
resulting in buggy mouse movements (cursor going straight out of the
screen), key pad only generating KEY_RIGHT and KEY_DOWN events.
A reproducer is:
int main(int argc, char ** argv)
{
        char rel_x = 0x00; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        rel_x = 0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        rel_x |= ~0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        return 0;
}
(running on x86 or amd64)
$ ./test
rel_x:0 @test.c:6
rel_x:15 @test.c:7
rel_x:-1 @test.c:8
(running on armv6)
rel_x:0 @test.c:6
rel_x:15 @test.c:7
rel_x:255 @test.c:8
Forcing the rel_x and rel_y variables as signed char fixes the issue.

      [media] mb86a20s: don't use state before initializing it · f167e302
      由 Mauro Carvalho Chehab 提交于 
      As reported by Feng's kbuild test:
	From: kbuild test robot <fengguang.wu@intel.com>
	Subject: drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: potential null dereference 'state'.  (kzalloc returns null)
	Date: Wed, 23 Jan 2013 19:30:43 +0800

	commit: f66d81b5 [media] mb86a20s: convert it to use dev_info/dev_err/dev_dbg

	drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: potential null dereference 'state'.  (kzalloc returns null)
	drivers/media/dvb-frontends/mb86a20s.c:706 mb86a20s_attach() error: we previously assumed 'state' could be null (see line 705)

As, at mb86a20s_attach(), we have an i2c pointer, use it for all printk
messages there, instead of state->i2c.
