From 0c997c0eaac8c68fa23719617484dae29bddaedd Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 22 Jul 2009 00:33:06 +0200 Subject: [PATCH] S3C24XX: GPIO: Fix pin range check in s3c_gpiolib_getchip In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is in the gpio banks range is reversed. Thus the function returns NULL for valid pins and the gpio chip if its not valid. As a result gpio states are not saved/restored properly during suspend/resume.
