Subject: [PATCH] staging: vt6656: Fix drivers TBTT timing counter.
Date: Sat, 18 Apr 2020 17:43:24 +0100 [thread overview]
Message-ID: <375d0b25-e8bc-c8f7-9b10-6cc705d486ee@gmail.com> (raw)
The drivers TBTT counter is not synchronized with mac80211 timestamp.
Reorder the functions and use vnt_update_next_tbtt to do the final
synchronize.
Fixes: c15158797df6 ("staging: vt6656: implement TSF counter")
