The following functions can be made static as they are only used locally:
hda_dsp_core_reset_enter
hda_dsp_core_reset_leave
hda_dsp_core_stall_reset
hda_dsp_core_power_up
hda_dsp_core_power_down
hda_dsp_core_is_enabled
The hda_dsp_ipc_int_disable is also only used within hda-dsp.c, but for
symmetry for hda_dsp_ipc_int_enable (used by hda-loader.c) leave it as it
is.
