Subject: staging: rtl8192u: remove unused code from cmpk_message_handle_tx()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f7e9fbc017b7f8e23c35d2f0be0f4842236b5a2c;p=linux-beck.git

staging: rtl8192u: remove unused code from cmpk_message_handle_tx()

The file r819xU_cmdpkt.c includes header r8192U.h which defines RTL8192U.
This patch removes from cmpk_message_handle_tx() the part of the code that
is never used because it resides outside the header guard #ifdef RTL8192U.
