Subject: timer: clarify error if subsystem already initialized
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5516e4760eb48c97bbaba195b18dda2302eeeb4f;p=dpdk.git

timer: clarify error if subsystem already initialized

rte_timer_subsystem_init() may return -EALREADY if it has been already
initialized. Therefore put explicitly into doxygen that this is not a
failure for the application.
