Subject: drivers/firmware: Don't mark as busy the simple-framebuffer IO
resource
Git-commit: c96898342c3813fa7de6a47904dea46538873b3b
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The sysfb_create_simplefb() function requests a IO memory resource for the
simple-framebuffer platform device, but it also marks it as busy which can
lead to drivers requesting the same memory resource to fail.
Let's drop the IORESOURCE_BUSY flag and let drivers to request it as busy
instead.
