[PATCH] PCI: xilinx-xdma: Use devm_platform_ioremap_resource_byname  

From: shao.mingyin
Date: Thu Apr 03 2025 - 03:47:16 EST


From: Xie Ludan <xie.ludan@xxxxxxxxxx>

Introduce devm_platform_ioremap_resource_byname() to simplify
resource retrieval and mapping.This new function consolidates
platform_get_resource_byname() and devm_ioremap_resource() into a single
call, improving code readability and reducing API call overhead.
