Subject: [PATCH V2 4/7] drm/radeon: Replace kmap() with kmap_local_page()
Date: Sun, 23 Jan 2022 17:54:06 -0800	[thread overview]
Message-ID: <20220124015409.807587-5-ira.weiny@intel.com> (raw)
In-Reply-To: <20220124015409.807587-1-ira.weiny@intel.com>

From: Ira Weiny <ira.weiny@intel.com>

kmap() is being deprecated and this usage is local to the thread.  Use
kmap_local_page() instead.
