[PATCH 5.6 140/167] staging: vt6656: Fix drivers TBTT timing counter.

[Greg Kroah-Hartman]

From: Malcolm Priestley <tvbox...@gmail.com>

commit 09057742af98a39ebffa27fac4f889dc873132de upstream.

The drivers TBTT counter is not synchronized with mac80211 timestamp.

Reorder the functions and use vnt_update_next_tbtt to do the final
synchronize.
