Hi all,

After merging the block tree, today's linux-next build (sparc defconfig)
failed like this:

drivers/scsi/qlogicpti.c: In function 'qpti_map_queues':
drivers/scsi/qlogicpti.c:828:24: error: 'return' with a value, in function returning void [-Werror=return-type]
828 | return -1;
| ^
drivers/scsi/qlogicpti.c:817:13: note: declared here
817 | static void qpti_map_queues(struct qlogicpti *qpti)
| ^~~~~~~~~~~~~~~
drivers/scsi/qlogicpti.c:839:24: error: 'return' with a value, in function returning void [-Werror=return-type]
839 | return -1;

drivers/scsi/qlogicpti.c:817:13: note: declared here

drivers/scsi/qlogicpti.c:1394:1: warning: label 'fail_free_irq' defined but not used [-Wunused-label]

cc1: some warnings being treated as errors

Caused by commit

f19f2c966b2f ("block: Change the return type of blk_mq_map_queues() into void")

I have applied the following fix up patch for today.
