[PATCH v3] HID: uclogic: properly format kernel-doc comment for hid_dbg() wrappers

[PATCH v3] HID: uclogic: properly format kernel-doc comment for hid_dbg() wrappers

[Bagas Sanjaya]

Running kernel-doc script on drivers/hid/hid-uclogic-params.c, it found
6 warnings for hid_dbg() wrapper functions below:

One of them is reported by kernel test robot.

Fix these warnings by properly format kernel-doc comment for these
functions.

None of this is needed for stable kernels releases as no code is being
modified.

Hi Greg,

That's right, however because I don't see any kernel-doc warnings for
hid-uclogic-params.c on linux-5.18.y. These warnings appear only on
mainline.

Thanks for reminding me.
