Thomas Bourgoin 91256fcd57 crypto: stm32/crc32 - fix parsing list of devices ... [ Upstream commit 0eaef675b9 ] smatch warnings: drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn: can 'crc' even be NULL? Use list_first_entry_or_null instead of list_first_entry to retrieve the first device registered. The function list_first_entry always return a non NULL pointer even if the list is empty. Hence checking if the pointer returned is NULL does not tell if the list is empty or not.
