Hi!
Rockchip ISP1 is broken for me on a custom rk3399-based board in the
latest media_stage. Relevant dmesg fragment:
rkisp1 ff910000.isp0: Adding to iommu group 2
genirq: Flags mismatch irq 42. 00000004 (rkisp1) vs. 00000084 (ff914000.iommu)
rkisp1 ff910000.isp0: request irq failed: -16
rkisp1: probe of ff910000.isp0 failed with error -16
rkisp1 ff920000.isp1: Adding to iommu group 3
genirq: Flags mismatch irq 43. 00000004 (rkisp1) vs. 00000084 (ff924000.iommu)
rkisp1 ff920000.isp1: request irq failed: -16
rkisp1: probe of ff920000.isp1 failed with error -16
According to rk3399.dtsi, isp interrupts are shared with correponding
mmu interrupts (isp0 with isp0_mmu, isp1 with isp1_mmu), so the subject
commit breaks devm_request_irq. Reverting it fixes the issue for me.
If I'm just missing something, sorry for the noise.
