Subject: ALSA: firewire-lib: use the same unit for payload argument in tracing events
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a8520f3e9314edddf95479c4796f05b7d594be32;p=openwrt%2Fstaging%2Fblogic.git

ALSA: firewire-lib: use the same unit for payload argument in tracing events

The most of tracing event in this module have the size of payload in
byte unit, however 'in_packet_without_header' event have the argument
in quadlet unit.

This commit change the unit for argument to be consistent.
