[Qemu-devel] [PATCH 00/12] block: Various Coverity-spotted fixes

[Max Reitz]

This series fixes various issues spotted by Coverity. None of these is
critical; most are just "If you do something crazy, qemu-img crashes" or
"But what if there is no qcow2 driver?". Therefore, while these are bug
fixes, it is a bit late to try to push them into 2.2.0. I am therefore
tempted to vote to target 2.3 instead.

Also, none is security-relevant. The only crashes which are fixed here
are sure to have resulted from dereferencing a NULL pointer.
