mtd: Fix kernel NULL pointer dereference in physmap.c
During the probe for physmap platform flash devices there are a
number error exit conditions that all do a goto err_out which
then calls physmap_flash_remove(). In that function one of the
cleanup steps is:
#ifdef CONFIG_MTD_CONCAT
if (info->cmtd != info->mtd[0])
mtd_concat_destroy(info->cmtd);
#endif
This test will succeed since info->cmtd == NULL and info->mtd[0] is
valid.
Fix this by exiting the remove function when info->cmtd == NULL.
Also, cleanup the #ifdef CONFIG_MTD_PARTITIONS stuff by using
mtd_has_partitions().
