Subject: genirq; Fix cleanup fallout
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ef5ca1e1f0de71300142b8f730f26ded6a0c2f3;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

genirq; Fix cleanup fallout

I missed the CONFIG_GENERIC_PENDING_IRQ dependency in the affinity
related functions and the IRQ_LEVEL propagation into irq_data
state. Did not pop up on my main test platforms. :(
