by fixeria

fixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/33583 ) Change subject: scheduler: unify argument names/order for _sched_compose_*_ind() ...................................................................... scheduler: unify argument names/order for _sched_compose_*_ind() This commit aims to make the argument naming/ordering more consistent: * rename l2/l2_len and tch/tch_len to data/data_len; * common arguments first (consistent ordering), specific last.
