Code inspection: '__grid_constant__' is only allowed on a kernel parameter

This inspection reports the __grid_constant__ specifier used anywhere except on a parameter of a __global__ function. The specifier makes the kernel use a single read-only copy of the parameter for the whole grid, so it is allowed only on kernel parameters.

Example

                struct Params { int data[8]; };

                __device__ void process(const __grid_constant__ Params params);

                struct Params { int data[8]; };

                __global__ void process(const __grid_constant__ Params params);

If the function is not a kernel, remove __grid_constant__.
