From aa07573b2bd0fee5a7537cb663fbb2de60278801 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 8 Apr 2009 14:12:47 +0200 Subject: [PATCH] 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 Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-probe.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/ide/ide-probe.c b/drivers/ide/ide-probe.c index d8c1c3e735b..c1ef8c8c785 100644 --- a/drivers/ide/ide-probe.c +++ b/drivers/ide/ide-probe.c @@ -1314,6 +1314,7 @@ struct ide_host *ide_host_alloc(const struct ide_port_info *d, hw_regs_t **hws) host->get_lock = d->get_lock; host->release_lock = d->release_lock; host->host_flags = d->host_flags; + host->irq_flags = d->irq_flags; } return host; -- 2.11.4.GIT
