H. Peter Anvin 2ee93ab67a acpi, bgrd: Add missing <linux/io.h> to drivers/acpi/bgrt.c
The ACPI BGRT driver uses ioremap() and memcpy_fromio(), which means
it needs to #include <linux/io.h>.

[ hpa: This was hidden because <asm/acpi.h> used to include <asm/trampoline.h>,
  which then included <asm/io.h> ]

Matthew Garrett d1ff4b1cdb ACPI: Add support for exposing BGRT data
ACPI 5.0 adds the BGRT, a table that contains a pointer to the firmware
boot splash and associated metadata. This simple driver exposes it via
/sys/firmware/acpi in order to allow bootsplash applications to draw their
splash around the firmware image and reduce the number of jarring graphical
transitions during boot.
