From 79d7f4ee23d41571d9e4663521b5e6604c55729a Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Tue, 30 Jun 2009 11:41:38 -0700 Subject: [PATCH] gpio: pl061: fix probe error handling code Note that IRQ has not been initialized when kmalloc() fails. Also, use DECLARE_BITMAP() to make the code clearer.
