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.
