Hi Xishi,

change

1474         if (first_colon && (!first_space || first_colon < first_space))
1475                 return parse_crashkernel_mem(ck_cmdline, system_ram,
1476                                 crash_size, crash_base);
1477         else
1478                 return parse_crashkernel_simple(ck_cmdline, crash_size,
1479                                 crash_base);
1480 
1481         return 0;

to

1474         if (first_colon && (!first_space || first_colon < first_space))
1475                 return parse_crashkernel_mem(ck_cmdline, system_ram,
1476                                 crash_size, crash_base);

1478         return parse_crashkernel_simple(ck_cmdline, crash_size, crash_base);

seems better.
