Hi Jan,

As it seems that there will be another revision anyway,
please update the above so that the local variable declarations
are in reverse xmas tree order - longest line to shortest.

Likewise in s32_dwmac_probe() in the patch
"net: stmmac: dwmac-s32: add basic NXP S32G/S32R glue driver".

...
