From 90f4a09a15239f4a819b2e90a7a0b92a75060655 Mon Sep 17 00:00:00 2001 From: Billy Tsai Date: Mon, 26 Sep 2022 18:51:45 +0800 Subject: [PATCH] i3c: master: Remove the wrong place of reattach. The reattach should be used when an I3C device has its address changed. But the modified place in this patch doesn't have the address changed of the newdev. This wrong reattach will reserve the same address slot twice and return unexpected -EBUSY when the bus find the duplicate device with diffent dynamic address.
