Arnd Bergmann 16b8b6de32 rocker: fix Wmaybe-uninitialized false-positive ... gcc-7 reports a warning that earlier versions did not have: drivers/net/ethernet/rocker/rocker_ofdpa.c: In function 'ofdpa_port_stp_update': arch/x86/include/asm/string_32.h:79:22: error: '*((void *)&prev_ctrls+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized] *((short *)to + 2) = *((short *)from + 2); ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/rocker/rocker_ofdpa.c:2218:7: note: '*((void *)&prev_ctrls+4)' was declared here This is clearly a variation of the warning about 'prev_state' that was shut up using uninitialized_var(). We can slightly simplify the code and get rid of the warning by unconditionally saving the prev_state and prev_ctrls variables. The inlined memcpy is not particularly expensive here, as it just has to read five bytes from one or two cache lines. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
