From 8bbc3c0850d0668ac7cf0f5b129ffae8c810247f Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Sun, 11 Nov 2018 08:55:11 +0100 Subject: [PATCH] mtd: rawnand: ams-delta: cleanup ams_delta_init() error path Remove unused labels, rename out_mtd into err_unmap to make it clearer and return 0 instead of using a goto out at the end of the registration procedure.
