v1 -> v2: modify comment This event is raised when link is lost as specified in UFSHCI spec and that means communication is not possible. Thus initializing UFS interface needs to be done. This patch is to make UFS driver see Link Lost as fatal by using INT_FATAL_ERRORS. This lead to host reset whenever a link lost interrupt occurs.
