From 3fc29573cf3e38624962f1a74ee18cbec2a2556e Mon Sep 17 00:00:00 2001 From: Matej Dujava Date: Sun, 3 May 2020 17:42:49 +0200 Subject: staging: vt6655: return early if not bNeedAck This patch will check for bNeedAck before making bb_get_frame_time call, so in case we dont need uAckTime, we can return early.
