[ Upstream commit baf5cb30fbd1c22f6aa03c081794c2ee0f5be4da ]
On RM400(a20r) machines ISA and SCSI interrupts share the same interrupt line. Commit 49e6e07e3c80 ("MIPS: pass non-NULL dev_id on shared request_irq()") accidently dropped the IRQF_SHARED bit, which breaks registering SCSI interrupt. Put back IRQF_SHARED and add dev_id for ISA interrupt.
