This warning was introduced by commit 533a6cfe08f9 "mmc: core: Default
to generic_cmd6_time as timeout in __mmc_switch()".  That should not be
applied to stable branches; it is not valid without (at least) these
preparatory changes:

0c204979c691 mmc: core: Cleanup BKOPS support
24ed3bd01d6a mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMC
ad91619aa9d7 mmc: block: Use generic_cmd6_time when modifying INAND_CMD38_ARG_EXT_CSD
