Subject: Reset buffer_alloc_sz after freeing buffer_alloc.
X-Git-Tag: v1.8.1~317^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=50b38cf1aa753f0c406b249d8e78a0689572d69b;p=libvpx

Reset buffer_alloc_sz after freeing buffer_alloc.

ybf->buffer_alloc and ybf->buffer_alloc_sz should ideally be kept in
sync. If ybf->buffer_alloc is reset to NULL after being freed, then
ybf->buffer_alloc_sz should be reset to 0.
