-Subject: [PATCH v2] pwm: img: Fix null pointer access in probe
-
-dev_get_drvdata() is called in img_pwm_runtime_resume() before the
-driver data is set.
-When pm_runtime_enabled() returns false in img_pwm_probe() it calls
-img_pwm_runtime_resume() which results in a null pointer access.
-
-This patch fixes the problem by setting the driver data earlier in the
-img_pwm_probe() function.
-
-This crash was seen when booting the Imagination Technologies Creator
-Ci40 (Marduk) with kernel 5.4 in OpenWrt.
-
-Fixes: e690ae526216 ("pwm: img: Add runtime PM")
