[PATCH 1/2] drm/sti: remove unused variable

[Arnd Bergmann]

One variable was left behind after its user got removed and we should now
delete the declaration as well:

drivers/gpu/drm/sti/sti_vtg.c: In function 'vtg_probe':
drivers/gpu/drm/sti/sti_vtg.c:392:22: error: unused variable 'np' [-Werror=unused-variable]

Fixes: 0c7ff84f7f9d ("drm/sti: remove deprecated legacy vtg slave")

[PATCH 2/2] drm/sti: remove unused sti_drm_dbg_cleanup

[Arnd Bergmann]

A cleanup patch just introduced this function, but no user, leading
to a compile-time warning:

drivers/gpu/drm/sti/sti_drv.c:120:13: error: 'sti_drm_dbg_cleanup' defined but not used [-Werror=unused-function]

It would be logical that we should actually call this function, but
I couldn't see from where, so this patch just shuts up the warning,
which may be the wrong approach.
