[PATCH] hid: Initialize battery_no to -1 & correct its format string

[PATCH] hid: Initialize battery_no to -1 & correct its format string

[Aniroop Mathur]

From: Aniroop Mathur <a.mathur@samsung.com>

This patch initializes battery_no to -1 to avoid extra subtraction
operation performed everytime wacom battery is initialized and
correct format string of unsigned long from %ld to %lu.

This is so femto-optimization, that I don't really care deeply. Adding 
Jason and Ping to CC. If they want this, I'll apply the patch.

[Aniroop Mathur]

Dear Mr. Jason and Mr. Ping,

Please update about below patch.
Except avoiding subtraction, there is also a need to avoid negative
battery name which may come due to %ld, so need to change to %lu.

Thanks,
Aniroop

Hi Benjamin,

The relevant code was introduced by
d70420b914c98a3758674c6e9858810e0ab4ea30. Can you take a look and let
us know if Aniroop's patch fits your original thought or not?

Thanks,

Ping

Hehe, indeed, that's my code.

I would agree with Jiri, I really do not care. This code is called
only once at initialization and I am pretty sure it will not change
the time to initialize the device (I am confident the compiler will do
something better than blindly following the code).

So either way it is good. But I have a slight preference to initialize
the variable to 0 and keep the unsigned in the name.

Cheers,
Benjamin

Atleast, there is a need to fix format specifier of "n" variable.
"n" is declared as unsigned long so %ld should be changed to %lu.
