[jeromecoutant]

While building with IAR 9.70, I got a warning here:
https://github.com/ARM-software/CMSIS-DSP/blob/main/Source/FilteringFunctions/arm_levinson_durbin_f16.c#L166

=> Source/FilteringFunctions/arm_levinson_durbin_f16.c",166 Warning[Go029]: Variable "vecRevA" is used uninitialized at this location in the sourcecode.

Thx
