[PATCH 1/5] staging: r8188eu: Fixed a function declaration coding style issue

[Chang Yu]

Added an identifier name for function definition argument
'struct timer_list *' as per checkpatch.pl

Note that for the same line checkpatch.pl will also complain "extern
should be avoided in .c". I am not very familiar with the codebase
so I decided not to move the declaration to a header file.

This really should be a static function, not a global one like this.
That is the correct fix to make, can you do that as an add-on patch?

thanks,
