question about drivers/i2c/busses/i2c-davinci.c

Julia Lawall <julia.lawall@xxxxxxx> · Sun, 6 Jan 2013 21:00:59 +0100 (CET)

The function davinci_i2c_remove in drivers/i2c/busses/i2c-davinci.c 
contains the following code:

        put_device(&pdev->dev);

        clk_disable_unprepare(dev->clk);
        clk_put(dev->clk);
        dev->clk = NULL;

        davinci_i2c_write_reg(dev, DAVINCI_I2C_MDR_REG, 0);
	free_irq(dev->irq, dev);

Is there any danger in putting free_irq(dev->irq, dev); after 
put_device(&pdev->dev);, because the interrupt handler i2c_davinci_isr can 
eg refer to dev->dev.

thanks,
julia
