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.
