From dcdd54c2bcae086a5834d3f823914d7535843b17 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 9 Feb 2018 14:24:41 +0100 Subject: rtlwifi: rtl8192cu: remove pointless memcpy gcc-8 points out that source and destination of the memcpy() are always the same pointer, so the effect of memcpy() is undefined here (its arguments must not overlap): drivers/net/wireless/realtek/rtlwifi/rtl8192cu/trx.c: In function '_rtl_rx_process': drivers/net/wireless/realtek/rtlwifi/rtl8192cu/trx.c:430:2: error: 'memcpy' source argument is the same as destination [-Werror=restrict] Most likely this is harmless, but it's easy to just remove the line and get rid of the warning.
