From edec5af7c5cba4a8c00c0c52fbad3b83217122da Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 30 Aug 2012 21:46:19 -0400 Subject: hwmon: (sht15) remove multiple driver registration Declare an array of platform_device_id, instead of registering a driver for each supported chip. This makes the code cleaner. Also add a module description.
