Subject: [PATCH v5 02/15] platform/x86: intel_cht_int33fe: Accept errors of i2c_acpi_new_device()
Date: Wed, 28 Nov 2018 13:45:22 +0200	[thread overview]
Message-ID: <20181128114535.80223-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20181128114535.80223-1-andriy.shevchenko@linux.intel.com>

In the future i2c_acpi_new_device() will return error pointer in some cases.
Prepare intel_cht_int33fe driver to support that.
