Hi Xueming,
I wanted to let you know that while backporting:

devargs: fix memory leak on parsing failure
I've found
[ 288s] ../lib/librte_eal/common/eal_common_devargs.c:171:16: error:
passing argument 1 of ‘free’ discards ‘const’ qualifier from pointer
target type [-Werror=discarded-qualifiers]
[ 288s] 171 | free(devargs->data);
[ 288s] | ~~~~~~~^~~~~~

argument is of type ‘const char *’

I've seen that to make it work it would require some more from the
same series, but that was not targeted at dpgk-stable

devargs: unify scratch buffer storage
Then I've checked and seen that it is also not present in
lib/librte_eal/common/eal_common_devargs.c of 20.11.2 that
you are preparing so I have also dropped it from 19.11.9 as well for now.
Do you think you'd want to create backports of this for 19.11/20.11 or
is it not important enough to bother about it?
