| commit 3030ca4cf4abbdd2dd850a14d20e9fca5937ffb5 upstream |
| |
| USB: storage: Avoid I/O errors when issuing SCSI ioctls to JMicron USB/ATA bridge |
| |
| Here's the patch that implements the fix you suggested to avoid the |
| I/O errors that I was running into with my new USB enclosure with a |
| JMicron USB/ATA bridge, while issuing scsi-io USN or other such |
| queries used by Fedora's mkinitrd. |
