From: Artem Bityutskiy Date: Sat, 18 Aug 2012 12:11:42 +0000 (+0200) Subject: UBI: fix autoresize handling in R/O mode X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=abb3e01103eb4e2ea5c15e6fedbc74e08bd4cc2b;p=linux-beck.git UBI: fix autoresize handling in R/O mode Currently UBI fails in autoresize when it is in R/O mode (e.g., because the underlying MTD device is R/O). This patch fixes the issue - we just skip autoresize and print a warning.
