[Qemu-block] [PULL 06/39] blockdev: clarify error on attempt to open locked tray

[Kevin Wolf]

From: Colin Lord <address@hidden>

When opening a device with a locked tray, gives an error explaining the
device tray is locked and that the user should wait and try again. This
is less confusing than the previous error, which simply stated that the
tray was locked.
