[PATCH v2 08/11] ata: pata_ixp4xx: Use devm_platform_get_and_ioremap_resource()

From: Yangtao Li
Date: Fri Jul 07 2023 - 05:56:40 EST


Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
