Subject: [PATCH 3/6] i2c: pca-platform: propagate error from i2c_pca_add_numbered_bus
Date: Fri, 30 Jun 2017 00:54:05 +0000	[thread overview]
Message-ID: <20170630005408.23968-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20170630005408.23968-1-chris.packham@alliedtelesis.co.nz>

Rather than returning -ENODEV if i2c_pca_add_numbered_bus() fails,
propagate the error to aid debugging.
