4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Finn Thain fthain@telegraphics.com.au
commit 8a500df63d07d8aee44b7ee2c54e462e47ce93ec upstream.
The SWIM chip is compatible with GCR-mode Sony 400K/800K drives but this driver only supports MFM mode. Therefore only Sony FDHD drives are supported. Skip incompatible drives.
