drivers/perf: Use devm_platform_get_and_ioremap_resource()

[PATCH -next] drivers/perf: Use devm_platform_get_and_ioremap_resource()

Posted by Yang Li 2 years, 6 months ago

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.
