From 9bdf9b4ec7c8b707cd0d9109d576c4eb69cd84bb Mon Sep 17 00:00:00 2001 From: Yadwinder Singh Brar Date: Thu, 5 Jul 2012 09:28:21 +0530 Subject: [PATCH] mfd: Apply irq_mask_cur before handling max77686 interrupts According to TRM, though we mask the interrupts in interrupt-mask register, interrupt source-register still provide the status of the masked interrupts. So we should apply irq_mask_cur to read interrupt source-register value before handling.
