genirq: Flags mismatch irq 4. 00000000 (serial) vs. 00000000 (lirc_sir)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Hi Jarod,

Since commit 4b71ca6 ("[media] lirc_sir: make device registration work"),
I see warnings "IRQ handler type mismatch for IRQ 4" in the
samsung/v4l-fimc-next branch.

The warning is made more obvious by Thomas' commit in linux-next
f5d89470f9 ("genirq: Be more informative on irq type mismatch"):
