From 0b43fef979b4664d51a09dc7e0c430ebb2d18267 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 12 Mar 2020 10:01:05 +0000 Subject: soundwire: stream: use sdw_write instead of update There is no point in using update for registers with write mask as 0xFF, this adds unnecessary traffic on the bus. Just use sdw_write directly.
