ACPI: EC: Fix ACPI EC resume non-query interrupt message
When resuming from standby (on a laptop) I see the following message in my kernel.log: "ACPI: EC: non-query interrupt received, switching to interrupt mode" This apparently prevented sony-laptop to properly restore the brightness level on resume. The cause: In drivers/acpi/ec.c the acpi_ec_suspend function clears the GPE mode bit, but this is not restored in acpi_ec_resume (the function below it). The patch below fixes this by properly restoring the GPE_MODE bit. Tested and confirmed to work. Signed-off-by: Almer S.
