[Qemu-devel] [PULL 1/4] dataplane/xen-block: remove dead code |
Date: |

From: Paul Durrant <address@hidden>
The if() statement is clearly bogus (dead code which should have been
cleaned up when grant mapping was removed).
Spotted by Coverity: CID 1398635
While in the neighbourhood, add a missing 'fall through' annotation.
