This patch breaks build if PCI support is not enabled: drivers/video/fbdev/efifb.c: In function ‘claim_efifb_bar’: drivers/video/fbdev/efifb.c:386:2: error: implicit declaration of function ‘pci_claim_resource’ [-Werror=implicit-function-declaration] (x86 ifdefs are not enough, the patch should also check for PCI support) Also please cc: linux-fbdev mailing list & me on fbdev related patches. > Cohen, Eugene (1): > efi/libstub: Skip GOP with PIXEL_BLT_ONLY format > > drivers/firmware/efi/libstub/gop.c | 6 ++-- > drivers/video/fbdev/efifb.c | 66 > +++++++++++++++++++++++++++++++++++++- > 2 files changed, 69 insertions(+), 3 deletions(-) Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics
