Subject[PATCH 4.9 19/25] block: rsxx: select CONFIG_CRC32
From: Arnd Bergmann <>

commit 36a106a4c1c100d55ba3d32a21ef748cfcd4fa99 upstream.

Without crc32, the driver fails to link:

arm-linux-gnueabi-ld: drivers/block/rsxx/config.o: in function `rsxx_load_config':
config.c:(.text+0x124): undefined reference to `crc32_le'

Fixes: 8722ff8cdbfa ("block: IBM RamSan 70/80 device driver")
