Fix these warnings by remove extraneous asterisk on static function
comments on patch [1/2] and add missing function name for void function
on patch [2/2].

[PATCH 1/2] HID: uclogic: remove extraneous asterisk on uclogic_params_* static functions comments

[Bagas Sanjaya]

*uclogic_params_pen_inrange_to_str(), uclogic_params_pen_hid_dbg(), and
uclogic_params_frame_hid_dbg() are static functions but contain
double-asterisk (/** */) comment, which confuses kernel-doc as public
function for generating documentation.

Remove the extraneous asterisk from these comments.

[PATCH 2/2] HID: uclogic: add missing function name in uclogic_params_hid_dbg() kernel-doc comment

[Bagas Sanjaya]

uclogic_params_hid_dbg() is public void function. The comment for
kernel-doc, however, lack its function name on short description, thus
triggers "missing initial short description" warning.

Add the function name to fix the warning.

So there is nothing wrong with making kerneldoc comments for static
functions, that is not where the problem lies.

A more likely problem here is the blank between the function intro and
the parameter description.

Here too

Here, instead, this needs to be formatted as a proper kerneldoc comment
with the function name.
