| |
From: Masahiro Yamada <masahiroy@kernel.org>
commit 28438794aba47a27e922857d27b31b74e8559143 upstream.
Since commit f02e8a6596b7 ("module: Sort exported symbols"), EXPORT_SYMBOL* is placed in the individual section ___ksymtab(_gpl)+<sym> (3 leading underscores instead of 2).
Since then, modpost cannot detect the bad combination of EXPORT_SYMBOL and __init/__exit.
Fix the .fromsec field.
