Subject[PATCH AUTOSEL for 3.18 14/40] i2c: mux: pca954x: Add missing pca9546 definition to chip_desc
Date
From: Mike Looijmans <mike.looijmans@topic.nl>

[ Upstream commit dbe4d69d252e9e65c6c46826980b77b11a142065 ]

The spec for the pca9546 was missing. This chip is the same as the pca9545
except that it lacks interrupt lines. While the i2c_device_id table mapped
the pca9546 to the pca9545 definition the compatible table did not.
