6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Xiaolei Wang <xiaolei.wang@windriver.com>

commit 726efa92e02b460811e8bc6990dd742f03b645ea upstream.

Currently imx8mp_blk_ctrl_remove() will continue the for loop
until an out-of-bounds exception occurs.
