Subject: AVR32 code: Mismatching comparison

Hi Haavard,

consider this piece of code from
arch/avr32/kernel/module.c:

....
case R_AVR32_GOT18SW:
    if ((relocation & 0xfffe0003) != 0
        && (relocation & 0xfffc0003) != 0xffff0000)
        return reloc_overflow(module, "R_AVR32_GOT18SW",
                    relocation);
    relocation >>= 2;
    /* fall through */
...

cppcheck reports for line 267:
"Mismatching comparison, the result is always true"

This probably needs a fix.

Cheers,
Thomas
