Description dcb314 2013-07-19 17:48:38 UTC
I just ran the static analysis checker "cppcheck" over
the source code of the Redhat Fedora package xorg-x11-drv-sis

It said

xorg-x11-drv-sis.spec.out:[sis_dac.c:1528] -> [sis_dac.c:
1532]: (warning) Variable 'max' is reassigned a value before the old one has bee
n used. 'break;' missing?

Source code is

        case PCI_CHIP_SIS660:
            if((pSiS->ChipType >= SIS_660) &&
               (pSiS->ChipFlags & SiSCF_760LFB)) {
               magic = magicDED[bus/64];
            } else {
               magic = magicINT[bus/64];
            max = 680000;
        case PCI_CHIP_SIS340:
        case PCI_CHIP_XGIXG40:
            magic = magicDED[bus/64];
            max = 800000;

Suggest add case statement to first case.
