[PATCH] Input: st-keyscan - Use devm_platform_get_and_ioremap_resource()

Posted by ye.xingchen@zte.com.cn 2 years, 7 months ago

From: ye xingchen <ye.xingchen@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.
