3.16.42-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> 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.
