While this should be a sane assumption, some devices don't follow spec and just use plain old hex. This causes drivers for these devices to generate invalid modalias lines which will never actually match for the hardware. The following patch adds hex support for bcdDevice in file2alias.c by detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and adjusts the output to hex format accordingly. Drivers for devices which have bcdDevice conforming to BCD will have no change in modalias output. Drivers for devices which don't conform (i.e. ibmcam) should now generate valid modaliases.
