[PATCH] module: replace VMLINUX_SYMBOL_STR() with __stringify() or string literal
From: Masahiro Yamada
Date: Sat Jun 23 2018 - 11:38:19 EST
With the special case handling for Blackfin and Metag was removed by
commit 94e58e0ac312 ("export.h: remove code for prefixing symbols with
underscore"), VMLINUX_SYMBOL_STR() is now equivalent to __stringify().
Replace the remaining usages to prepare for the entire removal of
VMLINUX_SYMBOL_STR().
