Subject: [PATCH 4/6] rtl8188eu: remove rtw_proc_init_one and rtw_proc_remove_one
rtw_proc_init_one() and rtw_proc_remove_one() are two very long
functions that are supposed to create a bunch of proc entries to
access debugging features of the driver.
But both of them are under #if 0 since their first commit three years
ago (5adef66acf73705ae95ea0b1e6b5fc7f17d82d30), replaced by two empty
functions.
Remove these two functions completely along with every reference to
them. This allows to cleanly remove lots of other functions which are
referenced only by the code under #if 0, and as such is already unused
code.
Subsequent commits remove the unused code.
Should anybody want to implement (in a proper way) the mentioned
debugging features, they can still fetch these functions from the git
history.
