Subject: [PATCH v8 4/4] drm: Remove drm_get_format_name()
Date:   Tue, 16 Feb 2021 12:19:31 +0200
Message-Id: <20210216101931.2110-5-sakari.ailus@linux.intel.com>

The %p4cc printk format modifier was recently added to print fourcc codes,
replacing drm_get_format_name(). The function is no longer needed, so
remove it.
