[PATCH 4.8 068/125] iio: light: us5182d: Add missing error code assignment before test

[Greg Kroah-Hartman]

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

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

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

commit 281269f8a0b00f5c95de5158e8595ed51bdb4b0a upstream.

It is likely that checking the result of 'pm_runtime_set_active' is
expected here.

Fixes: f0e5f57d3ac2 ("iio: light: us8152d: Add power management support")
