018361767a21fb2d5ebd3ac182c04baf8a8b4e08 upstream.
The RB532 platform specific irq_to_gpio() implementation has been
removed with commit
832f5dacfa0b ("MIPS: Remove all the uses of
custom gpio.h"). Now the platform uses the generic stub which causes
the following error:
pata-rb532-cf pata-rb532-cf: no GPIO found for irq149
pata-rb532-cf: probe of pata-rb532-cf failed with error -2
Drop the irq_to_gpio() call and get the GPIO number from platform
data instead. After this change, the driver works again:
scsi host0: pata-rb532-cf
ata1: PATA max PIO4 irq 149
ata1.00: CFA: CF 1GB,
20080820, max MWDMA4
ata1.00:
1989792 sectors, multi 0: LBA
ata1.00: configured for PIO4
scsi 0:0:0:0: Direct-Access ATA CF 1GB 0820 PQ: 0\
ANSI: 5
sd 0:0:0:0: [sda]
