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().
