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. * tag 'probes-fixes-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: probes: Fix to zero initialize a local variable
