Subject: [SPARC64]: Kill starfire_cookie from SBUS/PCI.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=286bbe87c143ca7ecee5bb499cd78048c5a05d49;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[SPARC64]: Kill starfire_cookie from SBUS/PCI.

Totally unused.

We need to traverse the list of global IRQ translaters,
so storing it in the per-bus structures was useless.
