ide: Fix host drivers that need IRQF_SHARED
commit 255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to specify IRQ flags") added irq_flags fields to struct ide_port_info and struct ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while init_irq() passes ide_host.irq_flags to request_irq(). Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM): | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | init_irq: sa = 0 | ide0: disabled, unable to get IRQ 15 | ide0: failed to initialize IDE interface | ide0: disabling port Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in ide_host_alloc(). This bug probably affects the following IDE host drivers: - buddha - delkin_cb - falconide - gayle - ide-cs - macide - q40ide - scc_pata - sgiioc4 Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
