Please use correct kernel-doc notation.
See Documentation/kernel-doc-nano-HOWTO.txt for details.
Briefly: "/**" begins a kernel-doc comment block.
Next line is "function short description" (when it's a function).
Parameters are referred to as @param, not \param.
Please check the entire patch series for this.

We prefer to have a variable name in the prototype (cf. below).
