Subject: UBIFS: return EROFS in case of broken commit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=549c999a768a7a144c60a0faa58f34c48f39112b;p=linux-beck.git

UBIFS: return EROFS in case of broken commit

If commit failed and it is in broken state, UBIFS switches to R/O mode. Most
operations return -EROFS in this case, except of commit which returns -EINVAL.
Make it return -EROFS too for consistency. This is also important for our power
cut emulation testing.
