[Qemu-devel] [PATCH v2 2/2] qdev: Constify local variable returned by blk_bs |
Date: |

Inside qdev_prop_set_drive() the value returned by blk_bs() is passed
only as pointer to const to bdrv_get_node_name() and pointed values is
not modified in other places so this can be made const for code
safeness.
