cc1: error: /git/arm-soc/drivers/staging/vc04_services/interface/vcos/linuxkernel: No such file or directory [-Werror=missing-include-dirs]

just remove the incorrect argument here.

The device sends data to the audio devices by sending a message with
the data through VC04_SERVICES/VCHIQ. This message contains a
callback pointer that is always filled in with the same function.
This is prone to corruption issues.
Instead fill the callback fields with a fixed cookie value to perforam
some validation on the message response and call the handler function
directly instead of through the callback pointer.

Initial cleanup of bcm2835-audio driver for the
bcm2535(Raspberry PI)
Driver provides HDMI audio through ALSA and is built
on top of the vc04_services driver.
Original version of the driver is available at:
http://www.github.com/raspberry/linux
Driver compiles without any build errors or warnings.
Tested on a RPI 3 running in ARM64 mode with the
vlc player and alsautils.
