Subject: [PATCH next] drm/panel: himax-hx83121a: Fix NULL vs IS_ERR() check in probe()
Date: Fri, 10 Apr 2026 13:12:08 +0300 [thread overview]
Message-ID: <adjM-IhvtrghMDnB@stanley.mountain> (raw)
The devm_drm_panel_alloc() function never returns NULL, it returns error
pointers on failure.
Fixes: a7c61963b727 ("drm/panel: Add Himax HX83121A panel driver")
Signed-off-by: Dan Carpenter <error27@gmail.com>
