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.
