You didn't read Kernel coding style doc?
around line 206 Documentation/CodingStyle
---------------------------
Use one space around (on each side of) most binary and ternary operators,
such as any of these:
= + - < > * / % | & ^ <= >= == != ? :
---------------------------

case SYS_DVBT2:
- /* FIXME: implement me */
- utmp = 0x08; /* DVB-C lock value */
+ msleep(150);
This sleep does not look correct. Why it is here? In order to provide
more time for lock waiting? In that case you must increase
.get_tune_settings() timeout. On some other case you will need to add
comment why such strange thing is needed.
