Subject[PATCH] pinctrl: iproc: improve error handling
Date
platform_get_irq() can return an error code. Allow for this when getting
the irq. While we're here use the dev_name(dev) for the irqc->name so
that we get unique names when we have multiple instances of this driver.

Noticed this while debugging another problem.
