Re: [PATCH V3 3/9] drm/vc4: Get the rid of DRM_ERROR()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Stefan,

On 8/21/24 18:40, Stefan Wahren wrote:
DRM_ERROR() has been deprecated in favor of pr_err(). However, we
should prefer to use drm_err() whenever possible so we get device-
specific output with the error message. In error case of kcalloc,
we can simply drop DRM_ERROR(), because kcalloc already logs errors.
