Subject: r600g/compute: Quick exit if there's nothing to add to the pool
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e7bda844e665c56c22d6ed0d801ee670d4137b1a;p=mesa.git

r600g/compute: Quick exit if there's nothing to add to the pool

This way we can avoid defragmenting the pool, even if it is needed
to defragment it, and looping again through the list of unallocated
items.
