6.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Bart Van Assche <bvanassche@xxxxxxx> [ Upstream commit 79519528a180c64a90863db2ce70887de6c49d16 ] Most callers of scsi_rescan_device() have the scsi_device pointer readily available. Pass a struct scsi_device pointer to scsi_rescan_device() instead of a struct device pointer. This change prevents that a pointer to another struct device would be passed accidentally to scsi_rescan_device(). Remove the scsi_rescan_device() declaration from the scsi_priv.h header file since it duplicates the declaration in <scsi/scsi_host.h>.
