From 27ed9ddfde8d2967076c51815e4ce297c4a18139 Mon Sep 17 00:00:00 2001 From: Benjamin Li Date: Thu, 18 Sep 2008 16:46:11 -0700 Subject: bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int The bnx2 driver stores/uses the irq value from the pci_dev internally. But when it stores the irq value, it has been performing an integer demotion. Because of the recent changes made to arch/x86/kernel/io_apic.c, the new method in creating the irq value (using build_irq_for_pci_dev()) has exposed this bug on x86 systems. Because of this demotion when calling request_irq() from bnx2_request_irq(), the driver would get a return code of -EINVAL. This is because the kernel could not find the requested irq descriptor. By storing the irq value properly, the kernel can find the correct irq descriptor and the bnx2 driver can operate normally.
