Subject: mmc: sh_mmcif: fix use after free
From: Guennadi Liakhovetski <[email protected]>
commit a0d28ba01ebd048b4ba418142b37f5cf80e6d156 upstream.
A recent commit "mmc: sh_mmcif: fix clock management" has introduced a
use after free bug in sh_mmcif.c: in sh_mmcif_remove() the call to
mmc_free_host() frees private driver data, therefore using it afterwards
is a bug. Revert that hunk.
