Check patch complains:
 +[2] bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN")
 +ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN")'

Either use commit sha ("title") or just drop the para.
