2016-11-27sndcp: fixup for coverity scan defect CID 149097Philipp1-0/+1
Coverity scan detects a Null pointer deref (FORWARD_NULL) in gprs_sndcp_comp.c: 67 in gprs_sndcp_comp_create(). The reason for this is that gprs_sndcp_dcomp_init() and also gprs_sndcp_pcomp_init() rely on the comp_entity->algo algo flag. If the program logic is correct a null pointer deref should never occur. This commit adds OSMO_ASSERT() statements to ensure a null pointer deref is catched if if the ...comp_init() functions are used with incorrect parameters.
