5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit aa578e897520f32ae12bec487f2474357d01ca9c ]
If an error occurs after request_mem_region(), a corresponding
release_mem_region() should be called, as already done in the remove
function.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
