add new_id to PCMCIA drivers
PCI drivers have the new_id file in sysfs which allows new IDs to be added at runtime. The advantage is to avoid re-compilation of a driver that works for a new device, but it's ID table doesn't contain the new device. This mechanism is only meant for testing, after the driver has been tested successfully, the ID should be added in source code so that new revisions of the kernel automatically detect the device. The implementation follows the PCI implementation. The interface is documented in Documentation/pcmcia/driver.txt. Computations should be done in userspace, so the sysfs string contains the raw structure members for matching.
