Replace the request_mem_region + ioremap calls by the
devm_request_and_ioremap call which does the same things but with device
managed resources.

This function is already deprecated, use devm_ioremap_resource() instead
(it returns error pointer, not NULL on error).
if (!hcd->regs) {
- pr_debug("ioremap failed\n");
+ dev_dbg(dev, "devm_request_and_ioremap failed\n");
There's no need -- those functions print error messages themselves.
