From aa07573b2bd0fee5a7537cb663fbb2de60278801 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 8 Apr 2009 14:12:47 +0200 Subject: 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().

This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...

However, references to the base of the structure were still using the '&' operator. When the address was used with the ata_id_u32() macro, the compiler used the size of the entire array instead of sizeof(u16) to calculate the offset from the base address. This patch removes the use of the '&' operator from all references of cf_id to fix the bug and remove future confusion.
