[PATCH v2] modpost: turn static exports into error

From: Quentin Perret
Date: Tue Dec 01 2020 - 11:53:23 EST


Using EXPORT_SYMBOL*() on static functions is fundamentally wrong.
Modpost currently reports that as a warning, but clearly this is not a
pattern we should allow, and all in-tree occurences should have been
fixed by now. So, promote the warn() message to error() to make sure
this never happens again.
