Subject: [PATCH 4.19 34/43] lightnvm: select CONFIG_CRC32

From: Arnd Bergmann <arnd@...db.de>

commit 19cd3403cb0d522dd5e10188eef85817de29e26e upstream.

Without CRC32 support, this fails to link:

arm-linux-gnueabi-ld: drivers/lightnvm/pblk-init.o: in function `pblk_init':
pblk-init.c:(.text+0x2654): undefined reference to `crc32_le'
arm-linux-gnueabi-ld: drivers/lightnvm/pblk-init.o: in function `pblk_exit':
pblk-init.c:(.text+0x2a7c): undefined reference to `crc32_le'

Fixes: a4bd217b4326 ("lightnvm: physical block device (pblk) target")
