GCC warns about functions without previous prototypes i.e -Wmissing-prototypes warnings.
In the following patches the following fixes have been adopted to eliminate these warnings: - Functions defined in a file, that are internal to that file have been made static. - Header files have been included in files whose non-internal functions have their prototypes defined in these headers files. - Adding prototypes for several non-internal functions in the appropriate header file while keeping the structure definitions of the parameters used by the functions in mind. - Add the prototype above the function definition. These warnings can be generated by adding -Wmissing-prototypes to KBUILD_FLAGS in the top-level Makefile and then perform the build.
