Subject: [PATCH v1 03/15] platform/x86: i2c-multi-instantiate: Accept errors of i2c_acpi_new_device()
Date: Tue, 20 Nov 2018 17:59:12 +0200 [thread overview]
Message-ID: <20181120155924.10773-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20181120155924.10773-1-andriy.shevchenko@linux.intel.com>
In the future i2c_acpi_new_device() will return error pointer in some cases.
Prepare i2c-multi-instantiate driver to support that.
