[PATCH 10/33] x86/amd: Set ELF function type for vide()

From: Josh Poimboeuf
Date: Thu Jan 21 2016 - 17:51:26 EST


vide() is a callable function, but is missing the ELF function type,
which confuses tools like stacktool.

Properly annotate it to be a callable function. The generated code is
unchanged.
