Re: [PATCH] Removed unnecessary void* from hashmap.h that caused compile warnings

[Thomas Gummerer <t.gummerer@gmail.com>]

Thanks for your patch!  A few nitpicks below:

> Subject: [PATCH] Removed unnecessary void* from hashmap.h that caused compile warnings

From Documentation/SubmittingPatches:

    Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
    instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
    to do frotz", as if you are giving orders to the codebase to change
    its behavior.

I liked the subject Philip suggested in the other thread: "hashmap.h:
remove unnecessary void*", or maybe "hashmap.h: remove unnecessary
variable".

As above, this should be described in an imperative mood, and describe
why this is a good change and should be merged.  Maybe something along
the lines of the below?

    In 'hashmap_enable_item_counting()', item is assigned but never
    used.  This causes a warning on HP NonStop.  As the variable is
    never used, fix this by just removing it.
