pata-rb532-cf: get rid of the irq_to_gpio() call
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] 1989792 512-byte logical blocks: (1.01 GB/971 MiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't\ support DPO or FUA sda: sda1 sda2 sd 0:0:0:0: [sda] Attached SCSI disk Fixes: 832f5dacfa0b ("MIPS: Remove all the uses of custom gpio.h") Cc: Alban Bedel <albeu@free.fr> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: <stable@vger.kernel.org> #v4.3+ Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Tejun Heo <tj@kernel.org>
