If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit cea9d2630607d4e89c227ff162a5222b8c2d9ee0 Author: Radhey Shyam Pandey <radhey.shyam.pandey@xxxxxxxxxx> Date: Thu Sep 26 16:20:59 2019 +0530 dmaengine: xilinx_dma: use devm_platform_ioremap_resource() [ Upstream commit a8bd47542863947e2433db35558477caf0d89995 ] Replace the chain of platform_get_resource() and devm_ioremap_resource() with devm_platform_ioremap_resource(). It simplifies the flow and there is no functional change.
