You don't need to, I fixed it when I committed the patch

Hi Avi, Marcelo,
here is v2 of the patches to support setting the guests tsc-frequency
from the qemu command line. This version addresses the comment from Avi
on the first version. To reflect that units can be given to the
frequency, the parameter was renamed from tsc_khz to tsc_freq.
Thanks,
This function does the same as the strtosz_suffix function
except that it allows to specify the unit to which the
k/M/B/T suffixes apply. This function will be used later to
parse the tsc-frequency from the command-line.

Done, and I fixed the use-after-free in patch #2.
