Subject: Remove unnecessary check of output parameter
X-Git-Tag: v2.11.0-rc2~200
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=d12522c8f767df18a4fa4af0df379e09aea26e6f;p=lttng-tools.git

Remove unnecessary check of output parameter

It is not necessary to check for `_notification != NULL` as it
is done at the beginning of the function. Moreover, it confuses
Coverity which warns that `notification` will be leaked if the
output parameter is NULL.
