Subject: tracing/irq: convert irq traces to use TRACE_EVENT macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=160031b556e93590fa8635210d73d93c3d3853a9;p=linux-beck.git

tracing/irq: convert irq traces to use TRACE_EVENT macro

The TRACE_FORMAT will soon be deprecated. This patch converts it to
the TRACE_EVENT macro.

Note, this change should also speed up the tracing.

[ Impact: remove a user of deprecated TRACE_FORMAT ]
