Subject: tracing: Skip printing "OK" if failed to disable event
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=76bab1b78ab6f25d5f74165f94526c25fc93d984;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tracing: Skip printing "OK" if failed to disable event

No acutal case found. But logically, we should skip "OK" in case any
error met.
