Subject: media: ipu3-cio2: Request IRQ earlier
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Tue Dec 20 16:01:20 2022 +0200
Call devm_request_irq() before registering the async notifier, as otherwise
it would be possible to use the device before the interrupts could be
delivered to the driver.
