2014-01-07drivers: gpu: Include appropriate header file in ci_smc.cRashika Kheria1-0/+1
Include header file drm/radeon/ci_dpm.h in drm/radeon/ci_smc.c because it uses function declared in the header file. This eliminates the following warnings in drm/radeon/ci_smc.c: drivers/gpu/drm/radeon/ci_smc.c:46:5: warning: no previous prototype for ‘ci_copy_bytes_to_smc’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:113:6: warning: no previous prototype for ‘ci_start_smc’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:121:6: warning: no previous prototype for ‘ci_reset_smc’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:129:5: warning: no previous prototype for ‘ci_program_jump_on_start’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:136:6: warning: no previous prototype for ‘ci_stop_smc_clock’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:145:6: warning: no previous prototype for ‘ci_start_smc_clock’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:154:6: warning: no previous prototype for ‘ci_is_smc_running’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:165:14: warning: no previous prototype for ‘ci_send_msg_to_smc’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:186:14: warning: no previous prototype for ‘ci_wait_for_smc_inactive’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:204:5: warning: no previous prototype for ‘ci_load_smc_ucode’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:251:5: warning: no previous prototype for ‘ci_read_smc_sram_dword’ [-Wmissing-prototypes] drivers/gpu/drm/radeon/ci_smc.c:266:5: warning: no previous prototype for ‘ci_write_smc_sram_dword’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
