From b0052b088cf0cb688b4630c1d520c57276da71a5 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Thu, 24 Mar 2011 02:34:33 +0000 Subject: [PATCH] can: c_can_platform: fix irq check in probe This patch fixes the check in the probe function whether a IRQ was supplied to the driver. The original driver check the irq "struct resource *" against <= 0. Use "platform_get_irq" instead. Signed-off-by: Marc Kleine-Budde Cc: Bhupesh Sharma Signed-off-by: David S.
