Subject: [PATCH][next] can: tcan45x: 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.

Fixes: 2de497356955 ("can: tcan45x: Make wake-up GPIO an optional GPIO")
