I'll fix this. I'll change your subject line to: mtd: mtd_blkdevs: fix double free on error path a) We use "mtd:" prefix, not "MTD:". b). mtd_blkdevs is not really an FTL layer, I think. c). The subject line has to make it obvious whether this is a bugfix or something else - it makes life of people who look at commit messages ans search for stuff important stuff easier. Your subject line is technically correct, but not very helpful. Anyway, picked to l2-mtd-2.6.git, thanks!
