Subject: [PATCH][next] can: tcan45x: Fix inconsistent IS_ERR and PTR_ERR
Date: Tue, 10 Dec 2019 09:05:32 -0600 [thread overview]
Message-ID: <20191210150532.GA12732@embeddedor> (raw)
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.
Fixes: 2de497356955 ("can: tcan45x: Make wake-up GPIO an optional GPIO")
