From c23cd8c971f0b4697f344d981f13aae4123f866d Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Tue, 25 Oct 2022 12:02:59 +0300 Subject: dmaengine: at_hdmac: Use pm_ptr() Use pm_ptr() macro to fill at_dma_driver.driver.pm. In case CONFIG_PM is not enabled, the macro will return NULL. When NULL, at_dma_dev_pm_ops will end up being unused, so prepend it with the __maybe_unused attribute.
