[Thomas Monjalon]

Hi,

Please could you rebase on master and keep the acked already given?
Please use --in-reply-to to keep v3 in the same thread as v2.

Titles are the same for every patches.
Are they all fixing a NULL pointer check and a mem leak?
More details in the commit message may help.

If they are fixes, a tag Fixes: may help for backports.

Thanks

Hi,
I've sent this patch again and it is accepted.
The other 3 pathes have no conflict with the latest master version and the titles have described the modification of the patches.
So I need not send the patches for v3, right?
