Subject: [PATCH net-next 1/4] net: dsa: sja1105: Get rid of global declaration of struct ptp_clock_info
Date: Sat, 12 Oct 2019 02:18:13 +0300 [thread overview]
Message-ID: <20191011231816.7888-2-olteanv@gmail.com> (raw)
In-Reply-To: <20191011231816.7888-1-olteanv@gmail.com>
We need priv->ptp_caps to hold a structure and not just a pointer,
because we use container_of in the various PTP callbacks.
Therefore, the sja1105_ptp_caps structure declared in the global memory
of the driver serves no further purpose after copying it into
priv->ptp_caps.
So just populate priv->ptp_caps with the needed operations and remove
sja1105_ptp_caps.
