Subject: [PATCH v1 1/4] media: ipu3-cio2: Don't dereference fwnode handle
Date:   Fri, 18 Nov 2022 20:56:14 +0200
Message-Id: <20221118185617.33908-1-andriy.shevchenko@linux.intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use acpi_fwnode_handle() instead of dereferencing an fwnode handle directly,
which is a better coding practice.
