[PATCH] mtd: rawnand: orion: use devm_platform_get_and_ioremap_resource()
Posted by ye.xingchen@zte.com.cn 3 years, 4 months ago
From: Minghao Chi <chi.minghao@zte.com.cn>

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.
