Subject: [PATCH v1 1/2] media: atomisp: Put PMIC device after getting its I²C address
Date: Tue, 26 Mar 2024 22:27:02 +0200	[thread overview]
Message-ID: <20240326202813.1425431-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240326202813.1425431-1-andriy.shevchenko@linux.intel.com>

We don't use the PMIC I²C client device after getting its address.
Drop the reference to it. We do not expect device to disappear
as it should be taken care by the OpRegion drivers.
