[PATCH 5.10 139/152] dm zoned: select CONFIG_CRC32

From: Greg Kroah-Hartman
Date: Mon Jan 18 2021 - 07:04:07 EST

From: Arnd Bergmann <arnd@xxxxxxxx>

commit b690bd546b227c32b860dae985a18bed8aa946fe upstream.

Without crc32 support, this driver fails to link:

arm-linux-gnueabi-ld: drivers/md/dm-zoned-metadata.o: in function `dmz_write_sb':
dm-zoned-metadata.c:(.text+0xe98): undefined reference to `crc32_le'
arm-linux-gnueabi-ld: drivers/md/dm-zoned-metadata.o: in function `dmz_check_sb':
dm-zoned-metadata.c:(.text+0x7978): undefined reference to `crc32_le'

Fixes: 3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")
