Subject: [PATCH 4.4 108/146] iio:ad7266: Fix broken regulator error handling
Date: Mon, 25 Jul 2016 13:56:03 -0700	[thread overview]
Message-ID: <20160725203525.843920252@linuxfoundation.org> (raw)
In-Reply-To: <20160725203521.340401316@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <broonie@kernel.org>

commit 6b7f4e25f3309f106a5c7ff42c8231494cf285d3 upstream.

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.
