Wysocki" , linux-acpi@vger.kernel.org Subject: [PATCH v1 1/1] device property: Unify access to of_node Date: Fri, 4 Jun 2021 16:13:43 +0300 Message-Id: <20210604131343.62016-1-andriy.shevchenko@linux.intel.com> X-Mailer: git-send-email 2.30.2 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-acpi@vger.kernel.org Historically we have a few variants how we access dev->fwnode and dev->of_node. Some of the functions during development gained different versions of the getters. Unify access to of_node and as a side change slightly refactor ACPI specific branches.
