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.
