diff --git a/drivers/hid/hidraw.c b/drivers/hid/hidraw.c index ec530454e6f6..5fbe0f81ab2e 100644 --- a/drivers/hid/hidraw.c +++ b/drivers/hid/hidraw.c @@ -337,8 +337,8 @@ static void drop_ref(struct hidraw *hidraw, int exists_bit) kfree(hidraw); } else { /* close device for last reader */ - hid_hw_power(hidraw->hid, PM_HINT_NORMAL); hid_hw_close(hidraw->hid); + hid_hw_power(hidraw->hid, PM_HINT_NORMAL); } } }
We should not try to bring HID device out of full power state before calling hid_hw_close(), so that transport driver operates on powered up device (making this inverse of the opening sequence).
