[ALSA] sound/isa/: cleanups
GUS Library
This patch contains the following possible cleanups:
- make needlesly global code static
- #if 0 the following unused global functions:
- gus/gus_volume.c: snd_gf1_gvol_to_lvol_raw
- gus/gus_volume.c: snd_gf1_calc_ramp_rate
- gus/gus_volume.c: snd_gf1_compute_vibrato
- gus/gus_volume.c: snd_gf1_compute_pitchbend
- gus/gus_volume.c: snd_gf1_compute_freq
- gus/gus_io.c: snd_gf1_i_adlib_write
- gus/gus_io.c: snd_gf1_i_write_addr
- gus/gus_io.c: snd_gf1_pokew
- gus/gus_io.c: snd_gf1_peekw
- gus/gus_io.c: snd_gf1_dram_setmem
- gus/gus_io.c: snd_gf1_print_global_registers
- gus/gus_io.c: snd_gf1_print_setup_registers
- gus/gus_io.c: snd_gf1_peek_print_block
- gus/gus_io.c: snd_gf1_print_setup_registers
- gus/gus_io.c: snd_gf1_peek_print_block
- #if 0 the following unused global variable:
- gus/gus_tables.h: snd_gf1_scale_table
- remove the following unneeded EXPORT_SYMBOL's:
- gus/gus_main.c: snd_gf1_i_write16
- gus/gus_main.c: snd_gf1_start
- gus/gus_main.c: snd_gf1_stop
