Subject: [PATCH 10/10] perf, tools, record: Always allow to overide default period v2
From: Andi Kleen <ak@...ux.intel.com>
Fix the logic to allow overriding event default periods with -c or -F
on the command line. I'm not sure I understand this if() fully, but
this change makes all cases I tested work (tracepoint with default, default,
,-c, -F)
This fixed specifying -c / -F with json event list events,
which have a default period. It should do the same
for trace point events.

v2: Simplify, just change || to &&
