[PATCH 3/3] kunit: tool: minor cosmetic cleanups in kunit_parser.py

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There should be no behavioral changes from this patch.

This patch removes redundant comment text, inlines a function used in
only one place, and other such minor tweaks.
