    dm: do not override error code returned from dm_get_device() · e80d1c80
    Vivek Goyal authored
    Some of the device mapper targets override the error code returned by
    dm_get_device() and return either -EINVAL or -ENXIO.  There is nothing
    gained by this override.  It is better to propagate the returned error
    code unchanged to caller.
    
    This work was motivated by hitting an issue where the underlying device
    was busy but -EINVAL was being returned.  After this change we get
    -EBUSY instead and it is easier to figure out the problem.
