Staging: ipack: implement ipack device table.
The modaliases look like ipack:fXvNdM, where X is the format version (8 bit) and N and M are the vendor and device ID represented as 32 bit hexadecimal numbers each. Using 32 bits allows us to define IPACK_ANY_ID as (~0) without interfering with the valid ids. The resulting modalias string for ipoctal.ko looks like this (once ipoctal provides a device table): alias: ipack:f01v000000F0d00000048* alias: ipack:f01v000000F0d0000002A* alias: ipack:f01v000000F0d00000022* (output from modinfo) Signed-off-by: Jens Taprogge <jens.taprogge@taprogge.org> Signed-off-by: Samuel Iglesias Gonsálvez <siglesias@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
