so when I enable the pr_debug()s in kernel/module,
and boot that kernel, I get a raft of messages (~800),
like :


[  110.072535] module:find_symbol: Failed to find symbol
drm_scdc_get_scrambling_status
[  110.072538] module:find_symbol: Failed to find symbol drm_scdc_read
[  110.072541] module:find_symbol: Failed to find symbol
drm_scdc_set_high_tmds_clock_ratio
[  110.072545] module:find_symbol: Failed to find symbol
drm_scdc_set_scrambling
[  110.072548] module:find_symbol: Failed to find symbol drm_scdc_write
[  110.072551] module:find_symbol: Failed to find symbol
drm_self_refresh_helper_alter_state
[  110.072553] module:find_symbol: Failed to find symbol
drm_self_refresh_helper_cleanup


What is the potential importance of these ?
clearly if it were a real problem, it wouldnt just be a debug message.
Is there anything to fix here, either in local config, or in code ?
