From 00af4b16e098f7899d78c7009f0b525c9c512f94 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Tue, 20 Nov 2012 15:46:44 +0900 Subject: extcon: max77693: Fix incorrect error check and return value irq_create_mapping() returns 0 if it fails to provide a valid irq number. 'ret' needs to be updated with a negative error code before returning from probe to signal probe failure. While at it, also corrected the 'virq' type to unsigned from signed.
