Mark reported that having asterisks on the end of directory names confuses get_maintainer.pl when it encounters subdirectories, and that my name does not appear when run on drivers/firmware/efi/libstub.

If anyone has any objections, please let me know. ------------------ From: Wang YanQing <udknight@gmail.com> commit c10fcb14c7afd6688c7b197a814358fecf244222 upstream. The code for checking whether a BAR address range is valid will break out of the loop when a start address of 0x0 is encountered. This behaviour is wrong since by breaking out of the loop we may miss the BAR that describes the EFI frame buffer in a later iteration. Because of this bug I can't use video=efifb: boot parameter to get efifb on my new ThinkPad E550 for my old linux system hard disk with 3.10 kernel. In 3.10, efifb is the only choice due to DRM/I915 not supporting the GPU. This patch also add a trivial optimization to break out after we find the frame buffer address range without testing later BARs.
