m68k/mac/: possible cleanups
This patch contains the following possible cleanups: - make the following needlessly global code (always) static: - baboon.c: struct baboon - baboon.c: baboon_irq() - config.c: mac_orig_videoaddr - config.c: mac_identify() - config.c: mac_report_hardware() - config.c: mac_debug_console_write() - config.c: mac_sccb_console_write() - config.c: mac_scca_console_write() - config.c: mac_init_scc_port() - oss.c: oss_irq() - oss.c: oss_nubus_irq() - psc.c: psc_debug_dump() - psc.c: psc_dma_die_die_die() - via.c: rbv_clear - remove the unused bootparse.c - #if 0 the following unused functions: - config.c: mac_debugging_short() - config.c: mac_debugging_long() - remove the following unused code: - config.c: mac_bisize - config.c: mac_env - config.c: mac_SCC_init_done - config.c: mac_SCC_reset_done - config.c: mac_init_scca_port() - config.c: mac_init_sccb_port() Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
