Simplify this function implementation by using the wrapper function “devm_platform_ioremap_resource” instead of calling the functions “platform_get_resource” and “devm_ioremap_resource” directly. * Thus reduce also a bit of exception handling code here. * Delete the local variable “res”. This issue was detected by using the Coccinelle software.
