Currently the order of the 'if' clauses in gsm48_gmm_authorize doesn't match the order in which the conditional parts are entered. This makes it difficult to maintain. In addition the t3350_mode is not stored in every path, so that this information is lost when the identification procedure is started. Since the default value coincidentally is GMM_T3350_MODE_ATT, this doesn't hurt for Attach Requests which are the only messages that initially trigger the authentication yet. This patch changes the order of the 'if' clause to match the processing order, it removes the t3350_mode parameter entirely and introduces a mm->pending_req field. The latter must be set when the request that causes the authorization before calling gsm48_gmm_authorize. The gprs_t3350_mode enum is extended by GMM_T3350_MODE_NONE (value 0, which is the default) to make it possible to detect related initialisation errors or race conditions. Sponsored-by: On-Waves ehf
