Subject: sched: Remove debug WARN_ONCE messages
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ac90ad6d754e81c5692a1e6a24499b53e0ffad6b;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

sched: Remove debug WARN_ONCE messages

If flow control functionality is not enabled in traffic controller
userspace modules, WARN_ONCE messages are triggered. Note that qdisc
will still be setup even if these debug messages are logged.
Remove these messages to reduce log spam.
