Subject: [PATCH v1 net] net: mscc: ocelot: remove buggy duplicate write to DEV_CLOCK_CFG
Date: Wed, 15 Sep 2021 18:23:40 -0700 [thread overview]
Message-ID: <20210916012341.518512-1-colin.foster@in-advantage.com> (raw)
When updating ocelot to use phylink, a second write to DEV_CLOCK_CFG was
mistakenly left in. It used the variable "speed" which, previously, would
would have been assigned a value of OCELOT_SPEED_1000. In phylink the
variable is be SPEED_1000, which is invalid for the
DEV_CLOCK_LINK_SPEED macro. Removing it as unnecessary and buggy.
Fixes: e6e12df625f2 ("net: mscc: ocelot: convert to phylink")
