drivers/clk/bcm/clk-bcm63xx-gate.c:174:1-9: WARNING: Use devm_platform_ioremap_resource for hw -> regs

 Use devm_platform_ioremap_resource helper which wraps
 platform_get_resource() and devm_ioremap_resource() together.

Generated by: scripts/coccinelle/api/devm_platform_ioremap_resource.cocci

Is it fixing anything? As far as I can tell it's reducing lines of code
with another function.

No, it doesn't fix anything.
