[PATCH 1/4] staging: gpib: fix kernel-doc section for write_loop() function

[Gaston Gonzalez]

Add a colon character in the kernel-doc section of write_loop() in order
'leng' to be picked as argument by the kernel-doc compiler.

This change fix the following warning:

warning: Function parameter or struct member 'leng' not described in
'send_command'

[PATCH 3/4] staging: gpib: fix kernel-doc section for usb_gpib_line_status() function

[Gaston Gonzalez]

The function name field in the kernel-doc section for the
usb_gpib_line_status() is defined as 'line_status'. In addition, after
the kernel-doc section, there are three macro definition instead of the
function definition.

These issues trigger the warning:

warning: expecting prototype for line_status(). Prototype was for WQT()
instead.

Fix the warning by renaming the function in the kernel-doc section and
by moving the macros at the beginning of the file with the rest of
macros definition.

Please disregard this patch. I noticed this blank line after I sent the
patch.

Will resend.
