media: pci: mg4b: Use IRQF_NO_THREAD

ef92b98f · Sebastian Andrzej Siewior <[email protected]> · 2026-01-28 10:55:40 +01:00

The interrupt handler iio_trigger_generic_data_rdy_poll() will invoke other
interrupt handlers and this supposed to happen from hard interrupt context.

Use IRQF_NO_THREAD to forbid forced-threading.
