Subject: [PATCH 1/2] gpio-ml-ioh: fix a bug in the interrupt handler
Date: Wed, 30 Nov 2011 15:51:40 +0800	[thread overview]
Message-ID: <1322639501-11940-1-git-send-email-feng.tang@intel.com> (raw)

GPIO's irq action's dev_id is set to the first struct ioh_gpio chip,
so when loop checking the 8 chips, the "chip" should be changed
according.
