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> --- Unsure about the Fixes tag, maybe it is 63e28a7a5ffc Change in v2: - add arch_phys_wc_del() at the right place in the error handling path v1 (a long time ago!): https://lore.kernel.org/all/dd2a4806d3a570ab84947806f38a494454fd0245.1622994310.git.christophe.jaillet@wanadoo.fr/ --- drivers/video/fbdev/uvesafb.c | 1 + 1 file changed, 1 insertion(+)
