Subject[PATCH 4.14 108/173] ubi: fastmap: Fix inverted logic in seen selfcheck
Date
From: Sascha Hauer <s.hauer@pengutronix.de>

commit ef5aafb6e4e9942a28cd300bdcda21ce6cbaf045 upstream.

set_seen() sets the bit corresponding to the PEB number in the bitmap,
so when self_check_seen() wants to find PEBs that haven't been seen we
have to print the PEBs that have their bit cleared, not the ones which
have it set.

Fixes: 5d71afb00840 ("ubi: Use bitmaps in Fastmap self-check code")
