REG_UFS_MTK_HW_VER is a read only mediatek dedicated register. So, hw_ver will get a const value for mediatek to decide how to use debug select. It only need read once, no need multi-threads protected.Hi Peter, The above can be concluded easily by a human but not by software. If this code is analyzed with KCSAN then KCSAN will probably complain. See also Documentation/dev-tools/kcsan.rst. Anyway, I'm fine with this patch. Thanks, Bart.
