Subject: [PATCH v3 05/25] i2c: designware: Fix lock probe call order in dw_i2c_plat_probe()
Date: Fri, 10 Nov 2023 20:11:25 +0200 [thread overview]
Message-ID: <20231110182304.3894319-6-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231110182304.3894319-1-andriy.shevchenko@linux.intel.com>
We should not mix managed calls with non-managed. This will break
the calls order at the error path and ->remove() stages. Fix this
by wrapping lock probe to become managed one.
Fixes: 78d5e9e299e3 ("i2c: designware: Add AMD PSP I2C bus support")
