From ddd244dd814ee3e5ef1e4872705cbec0dfced541 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Wed, 26 Nov 2008 17:06:42 +0800 Subject: [PATCH] [ARM] pxa: use 'pxa_last_gpio' instead of 'gpio_nr' in mfp-pxa2xx.c The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we already have that variable, remove the unnecessary 'gpio_nr' now. Also, fix the incorrect GPIO number passed in pxa27x_init_irq(). Note: pxa_last_gpio should be initialized earlier, and this is true since it's been assigned in machine_desc->init_irq().
