[Nicolas Ferre]

Hi all,

Well it seems my cover letter is missing. So, here it is:

pinctrl: at91-pio4: fixes for current linux-next (irq)

While testing the sama5d2 on today's linux-next I discovered that some
adaptations were missing. So, I don't know if you were aware but here
are my fixes in case you don't have them already.

+Cc: Thomas and Stephen in case these errors happen while building
linux-next...

Bye,
