Subject: [PATCH v2 1/4] iio: gyro: mpu3050: Fix incorrect free_irq() variable
Date: Mon, 23 Feb 2026 20:35:08 -0600	[thread overview]
Message-ID: <20260224023511.274038-2-ethantidmore06@gmail.com> (raw)
In-Reply-To: <20260224023511.274038-1-ethantidmore06@gmail.com>

The handler for the IRQ part of this driver is mpu3050->trig but,
in the teardown free_irq() is called with handler mpu3050:

	ret = request_threaded_irq(irq,
				   mpu3050_irq_handler,
				   mpu3050_irq_thread,
				   irq_trig,
				   mpu3050->trig->name,
				   mpu3050->trig);

...

void mpu3050_common_remove(struct device *dev)
{

...

	if (mpu3050->irq)
		free_irq(mpu3050->irq, mpu3050);
	iio_device_unregister(indio_dev);
	mpu3050_power_down(mpu3050);
}

Use correct IRQ handler when calling free_irq().
