From 7d4be2f5ad223942577c2319153b86592f3da5b2 Mon Sep 17 00:00:00 2001 From: Heiko Stübner Date: Sun, 3 Jun 2012 21:30:33 +0200 Subject: regulator: gpio-regulator: do not pass drvdata pointer as reference Commit c172708d38a4 (regulator: core: Use a struct to pass in regulator runtime configuration) added the drvdata pointer only per reference to the new config array in the gpio-regulator.

Therefore it stayed always at INT_MAX thus breaking the setting of the voltage. Included is also an init value for target, as warnings about a possibly uninitialised target started appearing with this fix.
