+Subject: [PATCH] drivers/firmware: Don't mark as busy the simple-framebuffer
+ IO resource
+
+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.
