Dear Haijun,

Check the below message, plz.

cmd_mmc.c: In function ?do_mmcops?:
cmd_mmc.c:405:5: warning: comparisons like ?X<=Y<=Z? do not have their mathematical meaning [-Wparentheses]
cmd_mmc.c:406:5: warning: comparisons like ?X<=Y<=Z? do not have their mathematical meaning [-Wparentheses]
cmd_mmc.c:407:4: warning: comparisons like ?X<=Y<=Z? do not have their mathematical meaning [-Wparentheses]
