stable inclusion from stable-5.10.80 commit bfedc817769dc2361ac7c1a473ce5e3e7f789da5 bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
