From 93bdc0eb0b4bb5e7094fd4a95f4a394e4a927e09 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 10 Dec 2019 09:05:32 -0600 Subject: [PATCH] can: tcan4x5x: tcan4x5x_parse_config(): fix inconsistent IS_ERR and PTR_ERR Fix inconsistent IS_ERR and PTR_ERR in tcan4x5x_parse_config(). The proper pointer to be passed as argument is tcan4x5x->device_wake_gpio. This bug was detected with the help of Coccinelle.
