[PATCH v3] drivers: mtd: Fixed breaking list in __mtd_del_partition.

From: Andreas Oetken
Date: Tue Nov 02 2021 - 13:26:13 EST


Not the child partition should be removed from the partition list
but the partition itself. Otherwise the partition list gets broken
and any subsequent remove operations leads to a kernel panic.
