[Qemu-devel] [PULL 32/76] m25p80: add missing blk_attach_dev_nofail

From: Paolo Bonzini <address@hidden>

Of the block devices that poked into -drive options via drive_get_next,
m25p80 was the only one who also did not attach itself to the BlockBackend.

Since sd does it, and all other devices go through a "drive" property,
with this change all block backends attached to the guest will have a
non-NULL result for blk_get_attached_dev().
