From a67ba97dfb30486deb4661f770b954387acc898d Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 6 Oct 2023 16:38:43 -0500 Subject: dmaengine: Use device_get_match_data() Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.
