Hello there,
I just ran the static analyser cppcheck over the source code of the
linux kernel version 3.6-rc1.
It said
linux-3.6-rc1/drivers/usb/host/ohci-tmio.c:105]: (warning) Redundant bitwise
operation on "pm" in switch
The source code is
switch (ohci->num_ports) {
default:
dev_err(&dev->dev, "Unsupported amount of ports: %d\n",
ohci->num_ports);
case 3:
pm |= CCR_PM_USBPW3;
case 2:
pm |= CCR_PM_USBPW2;
case 1:
pm |= CCR_PM_USBPW1;
}
Someone seems to have forgotten some break statements.
Suggest code rework.
Regards
David Binderman
