[PATCH] staging: r8188eu: remove forward declaration of Efuse_Read1ByteFromFakeContent

[Phillip Potter]

Remove forward declaration of Efuse_Read1ByteFromFakeContent function
from core/rtw_efuse.c, as the function is defined in full directly
after this and therefore this forward declaration is redundant.

Philip,

It's pretty clear that this function has only a translation unit visibility.
Why don't you make it clear by defining it with storage class "static"?

Thanks,

Fabio

Hi Phillip,

I agree with Fabio, making the function static avoids the 
[-Wmissing-prototypes] warning and makes it clear that it is only used 
in this file.

Thanks,

Michael

Dear Michael and Fabio,

You're both absolutely right, thank you for the feedback. It did occur
to me at the time that I could just make this static, and indeed the
change introduces a kernel test robot warning as it is currently, due
to -Wmissing-prototypes as mentioned. I shall rework, many thanks.

Regards,
Phil

Phil,

There a number of such forward references immediately followed by the actual 
routine. I removed some of these when the driver was in the GitHub repo, but I 
missed a few.

Dear Larry,

Thanks for this, I ended up doing a V2 that declares the function as
static as well. No doubt there will be others like this - I just
picked this one off as I happened to notice it :-)

Phil
