Hi all,

After merging the pm tree, today's linux-next build (i386 defconfig)
failed like this:

In file included from include/linux/i2c.h:13,
from include/uapi/linux/fb.h:6,
from include/linux/fb.h:7,
from include/linux/backlight.h:13,
from drivers/acpi/acpi_video.c:19:
drivers/acpi/acpi_video.c: In function 'acpi_video_device_EDID':
drivers/acpi/acpi_video.c:643:34: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'ssize_t' {aka 'int'} [-Werror=format=]
643 | "Invalid _DDC data for length %ld\n", length);

| %d

Caused by commit

9e9c41c069ce ("ACPI: video: Handle fetching EDID that is longer than 256 bytes")

Presumably it should be %zd.

I have reverted that commit for today.
