Subject: [PATCH v4 5/9] staging: iio: ad7780: move regulator to after GPIO init
Date: Thu, 28 Feb 2019 11:25:09 -0300 [thread overview]
Message-ID: <93cabb081605ac356f2f0d9a9a41d5bc5e63820d.1551358569.git.renatogeh@gmail.com> (raw)
In-Reply-To: <cover.1551358569.git.renatogeh@gmail.com>
To maintain consistency between ad7780_probe and ad7780_remove orders,
regulator initialization has been moved to after GPIO initializations.
