From: Frieder Schrempf <[email protected]>
distro_rauc_scan_parts() only sets desc if the bootflow has a block
device, but then checks desc before scanning the slots. Without a
block device, that check reads an uninitialised pointer and may hand
it to fs_set_blk_dev_with_part() and part_get_info().
Initialise desc to NULL, so that a bootflow without a block device
finds no slot, as the check intends.
Fixes: f271b0627001 ("bootstd: rauc: Only scan all partitions instead of boot
files")
