[PATCH 4.19 33/74] libata: add horkage for ASMedia 1092

From: Greg Kroah-Hartman
Date: Mon Dec 13 2021 - 04:41:50 EST


From: Hannes Reinecke <hare@xxxxxxx>

commit a66307d473077b7aeba74e9b09c841ab3d399c2d upstream.

The ASMedia 1092 has a configuration mode which will present a
dummy device; sadly the implementation falsely claims to provide
a device with 100M which doesn't actually exist.
So disable this device to avoid errors during boot.
