Subject: regulator: cpcap: Fix standby mode
From: Sebastian Reichel <sebastian.reichel@xxxxxxxxxxxxxxx>
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.
Fixes: 0ad4c07edd41 ("regulator: cpcap: Add basic regulator support")
