Subject: [IA64] Fix wrong assumption in acpi_gsi_to_irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c3738c874a2d42e84a2b02768f9807c334f3eff;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[IA64] Fix wrong assumption in acpi_gsi_to_irq

The ia64's acpi_gsi_to_irq() function assumes irq == vector. But in
fact irq can be different from vector. This patch fix this wrong
assumption.
