acpi_get_and_request_gpiod() does not take a gpio_lookup_flags argument specifying that the pins direction should be initialized to a specific value. This means that in some cases the pins might be left in input mode, causing the gpiod_set() calls made to enable the clk / regulator to not work. One example of this problem is the clk-enable GPIO for the ov01a1s sensor on a Dell Latitude 9420 being left in input mode causing the clk to never get enabled. Explicitly set the direction of the pins to output to fix this. Fixes: 5de691bf ("platform/x86: Add intel_skl_int3472 driver") Signed-off-by:
