Subject: [PATCH v1 12/15] platform/x86: i2c-multi-instantiate: Allow to have same slaves
Date: Tue, 20 Nov 2018 17:59:21 +0200	[thread overview]
Message-ID: <20181120155924.10773-13-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20181120155924.10773-1-andriy.shevchenko@linux.intel.com>

Currently the driver will not enumerate the devices where I2C slaves
are of the same type.

Add an instance number to make them unique.
