Subject: [PATCH next] drm/panel: nt37801: Fix IS_ERR() vs NULL check in probe()
Date: Fri, 23 May 2025 19:09:03 +0300	[thread overview]
Message-ID: <aDCdn9r_ZAUTRpWn@stanley.mountain> (raw)

The devm_drm_panel_alloc() function returns error pointers, it doesn't
return NULL.  Update the check to match.

Fixes: 4fca6849864d ("drm/panel: Add Novatek NT37801 panel driver")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
