V4L/DVB: lgs8gxx: Use shifts rather than multiply/divide when possible
If val is a u64, then following:
val *= (u64)1 << 32;
val /= (u64)1 << 32;
should surely be better represented as:
val <<= 32;
val >>= 32;
Especially as, for the division, the compiler might want to actually do a
division:
drivers/built-in.o: In function `lgs8gxx_get_afc_phase':
drivers/media/dvb/frontends/lgs8gxx.c:250: undefined reference to `__udivdi3'
