[Qemu-devel] [PULL 15/15] qdev: Constify local variable returned by blk_bs

[Eduardo Habkost]

From: Krzysztof Kozlowski <address@hidden>

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.
