Subject: Fix: potential use of uninitialized return value
X-Git-Tag: v2.12.0-rc1~17
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=235493868254e943513c6552c6821236284f00ac;p=lttng-tools.git

Fix: potential use of uninitialized return value

lttng_tracker_ids_serialize() can return an uninitialized value
when 0 ids are being tracked by a tracker. This is not currently
reachable, but generates a warning on some compilers.

'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
