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.
