From 49e19d5f27aaa004692a2080453b9cc4d4fb6ec4 Mon Sep 17 00:00:00 2001 From: Roberta Dobrescu Date: Thu, 12 Feb 2015 23:00:14 +0200 Subject: iio: light: jsa1212: Select REGMAP_I2C This patch adds missing 'select' statement for jsa1212 driver. Without regmap_i2c, we get the following error when loading the module: Unknown symbol devm_regmap_init_i2c.
