Subject: [net-next PATCH v2 09/12] net: phy: at803x: move specific at8031 config_intr to dedicated function
Date:   Fri,  1 Dec 2023 01:14:19 +0100
Message-Id: <20231201001423.20989-10-ansuelsmth@gmail.com>

Move specific at8031 config_intr bits to dedicated function to make
at803x_config_initr more generic.

This is needed in preparation for PHY driver split as qca8081 share the
same function to setup interrupts.
