Hi Jeff,
I observed the following warning for drivers/ata/libata-scsi.c:
drivers/ata/libata-scsi.c: In function ‘ata_scsi_scan_host’:
drivers/ata/libata-scsi.c:3272: warning: ‘dev’ may be used uninitialized in this function

In most instances=>
struct ata_device *dev
has been initialized except the above instance. My trivial patch below fixes this.
Please include it if you like it.

What was the conclusion of the analysis? :)
Is this a kernel bug, or gcc bug?
