Ah, I never ran checkpatch with --strict option...

CHECK: struct mutex definition without comment
#202: FILE: drivers/media/dvb-frontends/si2168_priv.h:32:
+	struct mutex i2c_mutex;

If you wish you could add some comment for it, but for me it is still 
pretty much self explaining. It is lock to protect firmware command 
execution. Command is executed always with I2C write and then poll reply 
using I2C read until it timeouts or answers with "ready" status.

regards
Antti
