From bcaec2ae3d975baca911162ad99d127b18fa376a Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Thu, 21 Sep 2023 08:56:57 +0300 Subject: [PATCH] i3c: mipi-i3c-hci: Remove BUG() when Ring Abort request times out [ Upstream commit 361acacaf7c706223968c8186f0d3b6e214e7403 ] Ring Abort request will timeout in case there is an error in the Host Controller interrupt delivery or Ring Header configuration. Using BUG() makes hard to debug those cases. Make it less severe and turn BUG() to WARN_ON().
