[PATCH 0/2] iio: mlx90632: Minor fixes

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

A couple of minor fixes.  The devm_ error handling was a coverity report.
Static was a warning I'd missed originally but saw in build whilst testing
the above.

Crt, could you give these a quick look (+tag ideally) then I'll get them
on the tree so the issue is fixed in Linux next before I send Greg a pull
request.

  iio: temperature: mlx90632: Add missing static marking on devm_pm_ops

[PATCH 1/2] iio: temperature: mlx90632: Add error handling for devm_pm_runtime_enable()

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This call can fail so handling is necessary even if it is very unlikely.

[PATCH 2/2] iio: temperature: mlx90632: Add missing static marking on devm_pm_ops

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Only used within this file, so should be marked static.
