From fde5d7f27108a444aa288ab9dfaa0a0c25e80b6d Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 9 Mar 2021 10:48:16 +0000 Subject: [PATCH] soundwire: bus: Fix device found flag correctly found flag is used to indicate SoundWire devices that are both enumerated on the bus and available in the device list. However this flag is not reset correctly after one iteration, This could miss some of the devices that are enumerated on the bus but not in device list. So reset this correctly to fix this issue!
