Hi All,

The latest mainline kernel branch fails to build for mips tb0226_defconfig
with the error:

mipsel-linux-ld: arch/mips/pci/fixup-tb0226.o: in function `pcibios_map_irq':
fixup-tb0226.c:(.text+0x38): undefined reference to `vr41xx_set_irq_trigger'

git bisect pointed to c4371c563973 ("gpio: remove VR41XX related gpio driver")

And, reverting that commit has fixed the build failure.

I will be happy to test any patch or provide any extra log if needed.
