Subject[PATCH] iio: adc: qcom-vadc: add missing MODULE_DESCRIPTION/LICENSE
Date
This change resolves a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/iio/adc/qcom-vadc-common.o
see include/linux/module.h for more information

This adds the license as "GPL v2", which matches the header of the file.

MODULE_DESCRIPTION is also added.
