In his response to the first submission Felipe Balbi asked to also move the driver to the new udc_start and udc_stop functions and to make an effort to reduce dependencies on archictecture code. The first patch reduces the number of arch dependencies by one by moving the platform data struct to a header unter include/linux/usb. The third patch adds a remove function, that was missing until now. The fifth and sixt patches implement the move to udc_start / udc_stop And the last patch finally allows the s3c-hsudc driver to control its supplying regulators as intended in the first place. The regulator calls can use the regulators unconditionally and let necessary "stubbing and mapping" happen through the regulator framework, according to for example http://marc.info/?l=linux-netdev&m=131914562120725&w=2 meaning there is no need to gracefully fail if a regulator is not present. Each patch was compile-tested individually, the series applies cleanly against linux-next from 2011-12-16. Real-life testing happened on S3C2416 hardware including adding and removing of gadgets and unloading and later on reloading the s3c_hsudc module.
