[PATCH 4.15 20/23] media: soc_camera: soc_scale_crop: add missing MODULE_DESCRIPTION/AUTHOR/LICENSE

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Jesse Chan <jc@linux.com>

commit 5331aec1bf9c9da557668174e0a4bfcee39f1121 upstream.

This change resolves a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/media/platform/soc_camera/soc_scale_crop.o
see include/linux/module.h for more information

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

MODULE_DESCRIPTION and MODULE_AUTHOR are also added.
