Subject: [PATCH] st: remove redundant pointer STbuffer

From: Colin Ian King <[email protected]>

Pointer STbuffer is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'STbuffer' set but not used [-Wunused-but-set-variable]

Has been unused at least since 2005 :-)

Thanks,
