From 2192a8ddc11ad7f243bed44eef4add8e37a658fe Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Wed, 9 Aug 2017 11:29:21 -0500 Subject: [PATCH] mtd: nand: sh_flctl: fix error return code in flctl_probe() platform_get_irq() returns an error code, but the sh_flctl driver ignores it and always returns -ENXIO. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Print and propagate the return value of platform_get_irq on failure. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
