From: Sebastian Reichel Date: Mon, 10 Jul 2017 14:33:39 +0000 (+0200) Subject: regulator: cpcap: Fix standby mode X-Git-Tag: Ubuntu-4.13.0-13.14~157 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=9b1b29025ce156929f92de132463c42ef5deb43b;p=mirror_ubuntu-artful-kernel.git regulator: cpcap: Fix standby mode BugLink: http://bugs.launchpad.net/bugs/1720154 commit 91a024e80336528d12b67b5a2e636b9e4467d3ec upstream. The original patch from Tony uses standby mode bit inverted, which is not correct. This fixes all instances in the driver code for get & set mode. This did not yet make problems, since mode has not been changed by any mainline driver so far.
