[PATCH] staging: vc04_services: remove unused functions

From: Alexander Alemayhu
Date: Tue Feb 07 2017 - 06:53:22 EST


Looking at the history these calls were introduced in 71bad7f08641
(staging: add bcm2708 vchiq driver, 2013-07-02) and they were not
being used at all.

Discovered using sparse and fixes the following output:

drivers/staging/vc04_services/interface/vchiq_arm/vchiq_shim.c:816:1: warning: symbol 'vchi_readbuf_uint32' was not declared. Should it be static?
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_shim.c:827:1: warning: symbol 'vchi_writebuf_uint32' was not declared. Should it be static?
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_shim.c:841:1: warning: symbol 'vchi_readbuf_uint16' was not declared. Should it be static?
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_shim.c:852:1: warning: symbol 'vchi_writebuf_uint16' was not declared. Should it be static?
