[patch 14/19] gpio/davinci: Prepare gpio_irq_handler for irq argument removal

From: Thomas Gleixner
Date: Mon Jul 13 2015 - 16:42:44 EST


The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.
