[PATCH net-next v2 1/3] net: altera-tse: Initialize the regmap_config struct before using it

From: Maxime Chevallier
Date: Tue Jun 06 2023 - 10:21:57 EST


The regmap_config needs to be zeroed before using it. This will cause
spurious errors at probe time as config->pad_bits is containing random
uninitialized data.

Fixes: db48abbaa18e ("net: ethernet: altera-tse: Convert to mdio-regmap and use PCS Lynx")
