Otherwise we would get an OOPS because of the missing adapter. And if so, what about the devm_release_mem_region() above. Can't they be removed, too? > --- > drivers/i2c/busses/i2c-mlxbf.c | 2 -- > 1 file changed, 2 deletions(-) > > diff --git a/drivers/i2c/busses/i2c-mlxbf.c b/drivers/i2c/busses/i2c-mlxbf.c > index 2fb0532..ea839de 100644 > --- a/drivers/i2c/busses/i2c-mlxbf.c > +++ b/drivers/i2c/busses/i2c-mlxbf.c > @@ -2426,8 +2426,6 @@ static int mlxbf_i2c_remove(struct platform_device *pdev) > } > mutex_unlock(&mlxbf_i2c_bus_lock); > > - devm_free_irq(dev, priv->irq, priv); > - > i2c_del_adapter(&priv->adap); > > return 0; > -- > 2.7.4 >

Use devm_request_irq to request interrupts,devm_free_irq is not needed to release interrupts. so just remove it. Signed-off-by: Tian Tao <tiantao6@hisilicon.com> --- drivers/i2c/busses/i2c-mlxbf.c | 2 -- 1 file changed, 2 deletions(-)
