fbdev: uvesafb: Fixes an error handling path in uvesafb_probe()
[ Upstream commit a94371040712031ba129c7e9d8ff04a06a2f8207 ] If an error occurs after a successful uvesafb_init_mtrr() call, it must be undone by a corresponding arch_phys_wc_del() call, as already done in the remove function. This has been added in the remove function in commit 63e28a7a5ffc ("uvesafb: Clean up MTRR code") Fixes: 8bdb3a2d7df4 ("uvesafb: the driver core") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Sasha Levin <sashal@kernel.org>
