From 3ee908dc3b48fa0a5be2883362d36e085b6b52f4 Mon Sep 17 00:00:00 2001 From: Hamad Kadmany Date: Fri, 20 Jan 2017 13:49:49 +0200 Subject: [PATCH] wil6210: protect against false interrupt during reset sequence During reset sequence it is seen that device is generating an interrupt eventhough interrupts are masked at device level. Add workaround to disable the interrupts from host side during reset and clear any pending interrupts before re-enabling the interrupt.
