[Qemu-devel] [PATCH] qdev: return size of binary properties.

[Qemu-devel] [PATCH] qdev: return size of binary properties.

[Gerd Hoffmann]

Make qdev_get_prop_bin() return the actual size of the binary property
instead of 0 on success.  Needed to handle variable length properties.

Incremental fix for the "qdev: add string and binary properties" patch.
