My two cents about using assert in the code, but I prefer to get some
info from system when something goes wrong as to call in some way panic
(the assert calls BUG_ON) and blocks forever.
This line is not different as checking the adapt_layer->dn pointer some
lines after and I think an error is better recognized in that case. So
IMHO should be better something like:

	if (channel_id == 0) {
		CFLOG_ERROR(("cfcnfg:adap_layer->dn is NULL\n"));
		return CFGLU_EINVAL;
	}

Probably you plan to use always the magic number in your buffer
management. Then should be better to remove all the #if CHECK_MEM stuff.

This three lines seem not needed.... ;)
