From ac66b628a9f3e9b153aec31aba9e4f3ff2a1fc09 Mon Sep 17 00:00:00 2001 From: Luca Ceresoli Date: Tue, 6 Sep 2016 18:36:55 +0200 Subject: [PATCH] staging: rtl8188eu: remove rtw_proc_{init,remove}_one MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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. Should they be moved out of #if 0 thay would not even compile, as they used functions that have been removed years ago (create_proc_read_entry()) and they use variables that are not defined (e.g. rtw_proc_cnt). rtw_proc_init_one() mentions several other functions that are not mentioned anywhere else in the kernel tree. Thus, after the present patch, all of those other functions can be cleanly removed as well, as they will be not mentioned anymore, not even in disabled code. Subsequent commits remove those other functions. Should anybody want to implement (in a proper way) the mentioned debugging features, they can still fetch this code from the git history.
