Subject: [PATCH 5/9] can: tcan4x5x: tcan4x5x_parse_config(): fix inconsistent IS_ERR and PTR_ERR
Date: Thu,  2 Jan 2020 17:09:30 +0100	[thread overview]
Message-ID: <20200102160934.1524-6-mkl@pengutronix.de> (raw)
In-Reply-To: <20200102160934.1524-1-mkl@pengutronix.de>

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>

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")
