Subject: Fix: common: unchecked return value
X-Git-Tag: v2.13.0-rc1~558
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=035cc184d874059a4155c86edd3f5d807886edd2;p=lttng-tools.git

Fix: common: unchecked return value

From Coverity:
  CID 1431050 (#1 of 1): Unchecked return value (CHECKED_RETURN)
  1. check_return: Calling lttng_dynamic_buffer_set_size without
     checking return value (as is done elsewhere 32 out of 40 times).

Solution
========

Since we are inside a the clear operation for the payload, ignore the
return value.
