The following series uses the recently introduced set of devm_irq_alloc_desc*() helpers in the GPIO drivers. While we're at it: if the modified drivers called request_irq(), it was changed to devm_request_irq() too. Some drivers correctly clean up resources (e.g. gpio-mockup, gpio-pch) - for them this change leads to an actual code shrink. Other drivers are meant to be built-in and the devices they control are never removed (e.g. gpio-pxa, gpio-davinci), so they deliberately omit the cleanup. Still: in case something changes it's better to free the resources - especially since these drivers already use other devm_* routines like devm_kzalloc() etc. The last group of drivers are the ones which can be compiled as modules, but leak resources unintentionally (e.g. gpio-twl4030, gpio-omap). This change fixes the interrupt descriptor leaks, but some drivers will require additional work since they still don't release other resources. The following drivers were tested: gpio-mockup, gpio-omap and gpio-davinci. The rest was compile-tested only.
