Subject: [PATCH v2 02/10] net: ethernet: ixgbe: don't call devm_mdiobus_free()
Date: Mon, 29 Jun 2020 14:03:38 +0200	[thread overview]
Message-ID: <20200629120346.4382-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20200629120346.4382-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

The idea behind devres is that the release callbacks are called if
probe fails. As we now check the return value of ixgbe_mii_bus_init(),
we can drop the call devm_mdiobus_free() in error path as the release
callback will be called automatically.
