[v2] scsi: scsi_devinfo: remove redundant 'found'

[PATCH v2] scsi: scsi_devinfo: remove redundant 'found'

Posted by mrigendrachaubey 7 months, 2 weeks ago

Remove the unnecessary 'found' flag in scsi_devinfo_lookup_by_key().
The loop can return the matching entry directly when found, and fall
through to return ERR_PTR(-EINVAL) otherwise.
