Message-Id: <20231006213844.333027-1-robh@kernel.org>
Date: Fri, 6 Oct 2023 16:38:43 -0500
From: Rob Herring <robh@...nel.org>
To: Vinod Koul <vkoul@...nel.org>,
Patrice Chotard <patrice.chotard@...s.st.com>
Cc: dmaengine@...r.kernel.org, linux-kernel@...r.kernel.org,
linux-arm-kernel@...ts.infradead.org
Subject: [PATCH] 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.
Signed-off-by: Rob Herring <robh@...nel.org>
