Subject: [PATCH 1/2] net: atlantic: remove deep parameter on suspend/resume functions
Date: Wed, 13 Jul 2022 19:12:23 +0800	[thread overview]
Message-ID: <20220713111224.1535938-1-acelan.kao@canonical.com> (raw)

From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com>

Below commit claims that atlantic NIC requires to reset the device on pm
op, and had set the deep to true for all suspend/resume functions.
commit 1809c30b6e5a ("net: atlantic: always deep reset on pm op, fixing up my null deref regression")
So, we could remove deep parameter on suspend/resume functions without
any functional change.

Fixes: 1809c30b6e5a ("net: atlantic: always deep reset on pm op, fixing up my null deref regression")
