Merge tag 'probes-fixes-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull probes fixlet from Masami Hiramatsu:
- tracing/probes: initialize a 'val' local variable with zero.
This variable is read by FETCH_OP_ST_EDATA in a loop, and is
initialized by FETCH_OP_ARG in the same loop. Since this
initialization is not obvious, smatch warns about it.
Explicitly initializing 'val' with zero fixes this warning.
