Subject[PATCH] gpu: drm: i915: intel_sideband.c: Remove some unused functions
Date
Removes some functions that are not used anywhere:
vlv_flisdsi_read() vlv_gps_core_write() vlv_gps_core_read()
vlv_ccu_write() vlv_ccu_read() vlv_gpio_nc_read()

This was partially found by using a static code analysis program called cppcheck.
