I guess you worked on linux-next which contains a change outside the sound git tree that converts ioremap_nocache() to ioremap(). We may apply it in sound git tree and let conflicts resolved at the merge time. OTOH, it's no urgent fix at all and can be postponed after 5.6-rc1 merge, too -- then everything can be applied in a cleaner way. Let me know your preference. thanks, Takashi > > --- > sound/drivers/ml403-ac97cr.c | 4 +--- > 1 file changed, 1 insertion(+), 3 deletions(-) > > diff --git a/sound/drivers/ml403-ac97cr.c b/sound/drivers/ml403-ac97cr.c > index 4e6042e652f0..9de5caaf6047 100644 > --- a/sound/drivers/ml403-ac97cr.c > +++ b/sound/drivers/ml403-ac97cr.c > @@ -1100,9 +1100,7 @@ snd_ml403_ac97cr_create(struct snd_card *card, struct platform_device *pfdev, > PDEBUG(INIT_INFO, "Trying to reserve resources now ...\n"); > resource = platform_get_resource(pfdev, IORESOURCE_MEM, 0); > /* get "port" */ > - ml403_ac97cr->port = ioremap(resource->start, > - (resource->end) - > - (resource->start) + 1); > + ml403_ac97cr->port = ioremap(resource->start, resource_size(resource)); > if (ml403_ac97cr->port == NULL) { > snd_printk(KERN_ERR SND_ML403_AC97CR_DRIVER ": " > "unable to remap memory region (%pR)\n", > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
