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

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

From: Esben Haabendal <esben@geanix.com>

[ Upstream commit 8a9bcd587d7d768e6c8e9fff88bb89645e412731 ]

In case devm_request_threaded_irq() failed, we were leaving the chip
powered instead of powering it down again. Power down the chip switching
ALS and PS modes to standby.
