From f4c812bef76a2cd95f675cb27ea89059561ceec7 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 13 Feb 2015 23:51:10 -0800 Subject: altos: Replace ao_alarm/ao_clear_alarm with ao_sleep_for Having arbitrary alarms firing in the middle of complicated device logic makes no sense at all. Therefore only correct use of ao_alarm and ao_clear_alarm was around a specific ao_sleep call, with correct recovery in case the alarm fires. This patch replaces all uses of ao_alarm/ao_sleep/ao_clear_alarm with ao_sleep_for, a new function which takes the alarm timeout directly. A few cases which weren't simply calling ao_sleep have been reworked to pass the timeout value down to the place where sleep *is* being called, and having that code deal with the return correctly.
