ice: fix dpll periodic work data updates on PF reset
[ Upstream commit 9a8385f ] Do not allow dpll periodic work function to acquire data from firmware if PF reset is in progress. Acquiring data will cause dmesg errors as the firmware cannot respond or process the request properly during the reset time. Test by looping execution of below step until dmesg error appears: - perform PF reset $ echo 1 > /sys/class/net/<ice PF>/device/reset Fixes: d7999f5 ("ice: implement dpll interface to control cgu") Reviewed-by: Igor Bagnucki <igor.bagnucki@intel.com> Signed-off-by: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
