Subject: mtd: mtd_blkdevs: fix double free on error path
From: Maxim Levitsky <[email protected]>
commit bd637f6f22235b4613f9ab6555e8088a455c1ed4 upstream.
This one liner patch fixes double free that will occur if add_mtd_blktrans_dev
fails. On failure it frees the input argument, but all its users also free it
on error which is natural thing to do. Thus don't free it.
All credit for finding that bug belongs to reporters of the bug in the android
bugzilla
