[PATCH v3] workaround for Sphinx false positive preventing indexing

[Kevin Paul Reddy Janagari <kevinpaul468@gmail.com>]

Functions drm_format_info, drm_modeset_lock, drm_ioctl_flags are not being
indexed in the documentation because there are structs with the same name
and sphinx is only indexing one of them, Added them to namespaces as a
workaround for suppressing the warnings and indexing the functions

This is a bug of Sphinx >=3.1, first reported by Mauro in September 2020
