Linus Torvalds 962490525c Probes fixes for v6.9-rc1: 
- tracing/probes: initialize a 'val' local variable with zero. This variable
    is read by FETCH_OP_ST_EDATA in a loop, and is expected to be initialized
    by FETCH_OP_ARG in the same loop. Since this expectation is not obvious,
    thus smatch warns it. Initializing 'val' with zero fixes this warning.

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.
