This is a note to let you know that I've just added the patch titled efi/gop: Return EFI_SUCCESS if a usable GOP was found to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: efi-gop-return-efi_success-if-a-usable-gop-was-found.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e6dce2a4f522a604bee34b40b4f27b1d77499674 Author: Arvind Sankar <nivedita@xxxxxxxxxxxx> Date: Fri Dec 6 16:55:39 2019 +0000 efi/gop: Return EFI_SUCCESS if a usable GOP was found [ Upstream commit dbd89c303b4420f6cdb689fd398349fc83b059dd ] If we've found a usable instance of the Graphics Output Protocol (GOP) with a framebuffer, it is possible that one of the later EFI calls fails while checking if any support console output. In this case status may be an EFI error code even though we found a usable GOP. Fix this by explicitly return EFI_SUCCESS if a usable GOP has been located.
