lightnvm: pblk: fix resource leak of invalid_bitmap
Currently the error exit path when the emeta could not be interpreted is via fail_free_ws and this fails to free invalid_bitmap. Fix this by adding another exit label and exiting via this to kfree invalid_bitmap. Detected by CoverityScan, CID#1469659 ("Resource leak") Fixes: 48b8d20895f8 ("lightnvm: pblk: garbage collect lines with failed writes") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
