    pinctrl: microchip-sgpio: check return value of devm_kasprintf()
    
    [ Upstream commit 310cd4c206cd04696ccbfd1927b5ab6973e8cc8e ]
    
    devm_kasprintf() returns a pointer to dynamically allocated memory.
    Pointer could be NULL in case allocation fails. Check pointer validity.
    Identified with coccinelle (kmerr.cocci script).
