From e43ea7a7736bb29fd088e83a7b66195eb2854814 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 13 Jul 2015 00:06:41 +0200 Subject: gpio/ep93xx: Prepare ep93xx_gpio_f_irq_handler for irq argument removal 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.
