commit: abb3e01103eb4e2ea5c15e6fedbc74e08bd4cc2b From: Artem Bityutskiy <[email protected]> Date: Sat, 18 Aug 2012 14:11:42 +0200 Subject: UBI: fix autoresize handling in R/O mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
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.
