<div class='commit-subject'>[media] s5k4ecgx: select CRC32 helper</div><div class='commit-msg'>A rare randconfig build failure shows up in this driver when
the CRC32 helper is not there:

drivers/media/built-in.o: In function `s5k4ecgx_s_power':
s5k4ecgx.c:(.text+0x9eb4): undefined reference to `crc32_le'

This adds the 'select' that all other users of this function have.
