From 8837f03001de875b0eb6d180a726ac92da6a562e Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Tue, 19 May 2020 15:00:09 +0200 Subject: [PATCH] mtd: rawnand: oxnas: Fix the probe error path commit 154298e2a3f6c9ce1d76cdb48d89fd5b107ea1a3 upstream. nand_release() is supposed be called after MTD device registration. Here, only nand_scan() happened, so use nand_cleanup() instead. While at it, be consistent and move the function call in the error path thanks to a goto statement.
