Subject: iwlwifi: pcie: fix (again) prepare card flow
From: Emmanuel Grumbach <[email protected]>
commit 03a19cbb91994212be72ce15ac3406fa9f8ba079 upstream.
The hardware bug in the commit mentioned below forces us
not to re-enable the clock gating in the Host Cluster.
The impact on the power consumption is minimal and it allows
the WAKE_ME interrupt to propagate.
