When using --strict, CamelCase uses are described with CHECK: messages. These CamelCase uses may be acceptable and should not generate these messages when the variable is already defined in a file from the include/... path. So, change checkpatch to read all the .h files in include/... and look for preexisting CamelCase #defines, typedefs and function prototypes. Add these to the existing camelcase hash so that any uses in the patch or file can be ignored. There are currently ~3500 files in include/. It takes about 10 cpu seconds on my little netbook to grep for and preseed these existing uses. That's about 4x the time for a similar git grep. This preseeding is only done once when using --strict and only when there is a CamelCase use found.

The RapidIO modalias string format is shown below: "rapidio:vNNNNdNNNNavNNNNadNNNN" Where: v - Device Vendor ID (16 bit), d - Device ID (16 bit), av - Assembly Vendor ID (16 bit), ad - Assembly ID (16 bit), as they are reported in corresponding Capability Registers (CARs) of each RapidIO device.
