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
