Subject: linux-next: build failure after merge of the pm tree

Hi all,

After merging the pm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/fpga/lattice-sysconfig-spi.c:146:35: error: implicit declaration of function 'of_match_ptr' [-Werror=implicit-function-declaration]

Caused by commit (I am pretty sure, but can't see why)

  054e68aae050 ("ACPI: Replace irqdomain.h include with struct declarations")

I have applied the following patch for today (and it could be applied
to the pm tree).
