iio:ad7266: Fix broken regulator error handling
[ Upstream commit 6b7f4e25f3309f106a5c7ff42c8231494cf285d3 ]
All regulator_get() variants return either a pointer to a regulator or an
ERR_PTR() so testing for NULL makes no sense and may lead to bugs if we
use NULL as a valid regulator. Fix this by using IS_ERR() as expected.
