If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Fri Apr 9 11:45:07 AM CEST 2021 From: Miquel Raynal <miquel.raynal@xxxxxxxxxxx> Date: Tue, 19 May 2020 15:00:13 +0200 Subject: mtd: rawnand: pasemi: Fix the probe error path From: Miquel Raynal <miquel.raynal@xxxxxxxxxxx> commit f51466901c07e6930435d30b02a21f0841174f61 upstream nand_cleanup() is supposed to be called on error after a successful call to nand_scan() to free all NAND resources. There is no real Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible, hence pointing it as the commit to fix for backporting purposes, even if this commit is not introducing any bug.
