[PATCH net-next v2 11/17] net: dsa: microchip: ksz9477: remove MII_CTRL1000 check from ksz9477_w_phy()

From: Oleksij Rempel
Date: Mon Aug 22 2022 - 07:05:11 EST


The reason why PHYlib may access MII_CTRL1000 on the chip without GBit
support is only if chip provides wrong information about extended caps
register. This issue is now handled by ksz9477_r_phy_quirks()

With proper regmap_ranges provided for all chips we will be able to catch this
kind of bugs any way. So, remove this sanity check.
