Subject: [PATCH] phy: samsung: exynos5250-sata: fix missing device put in probe error paths
Date: Wed,  9 Mar 2022 18:00:28 +0100	[thread overview]
Message-ID: <20220309170028.51913-1-krzysztof.kozlowski@canonical.com> (raw)

The actions of of_find_i2c_device_by_node() in probe function should be
reversed in error paths by putting the reference to obtained device.

Fixes: bcff4cba41bc ("PHY: Exynos: Add Exynos5250 SATA PHY driver")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
