From 89553114efe781baae223fc1867e37e64546a09e Mon Sep 17 00:00:00 2001 From: Dedy Lansky Date: Mon, 4 Sep 2017 12:00:50 +0300 Subject: [PATCH] wil6210: clear PAL_UNIT_ICR part of device reset When FW starts running it can get D0 to D3 interrupt that is a leftover from previous system suspend while FW was not running. As this interrupt is not relevant anymore, clear it part of device reset procedure.
