[PATCH 3.12 015/113] s5k4ecgx: select CRC32 helper

[Jiri Slaby]

From: Arnd Bergmann <arnd@xxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit c739c0a7c3c2472d7562b8f802cdce44d2597c8b upstream.

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.

Fixes: 8b99312b7214 ("[media] Add v4l2 subdev driver for S5K4ECGX sensor")
