Subject: [PATCH 5.10 386/575] iio: st_sensors: Call st_sensors_power_enable() from bus drivers
From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
[ Upstream commit 7db4f2cacbede1c6d95552c0d10e77398665a733 ]
In case we would initialize two IIO devices from one physical device,
we shouldn't have a clash on regulators. That's why move
st_sensors_power_enable() call from core to bus drivers.
