Subject: [PATCH net v2 2/2] net: phy: micrel: Pass .probe for KS8737
Date: Wed, 4 May 2022 11:31:04 -0300 [thread overview]
Message-ID: <20220504143104.1286960-2-festevam@gmail.com> (raw)
In-Reply-To: <20220504143104.1286960-1-festevam@gmail.com>
From: Fabio Estevam <festevam@denx.de>
Since commit f1131b9c23fb ("net: phy: micrel: use
kszphy_suspend()/kszphy_resume for irq aware devices") the kszphy_suspend/
resume hooks are used.
These functions require the probe function to be called so that
priv can be allocated.
Otherwise, a NULL pointer dereference happens inside
kszphy_config_reset().
