This description is missing the most vital bits of information. In years to come, someone will wonder "why has this changed" and there's no reason given in the commit log. Commit logs which are just mere translations from patch to English are evil. Instead, good commit logs briefly state what is being done and then go on to describe _why_ the change is necessary. > Signed-off-by: Shubhrajyoti D <shubhrajyoti@xxxxxx> > --- > drivers/i2c/busses/i2c-omap.c | 3 +++ > 1 files changed, 3 insertions(+), 0 deletions(-) > > diff --git a/drivers/i2c/busses/i2c-omap.c b/drivers/i2c/busses/i2c-omap.c > index b6c6b95..ce41596 100644 > --- a/drivers/i2c/busses/i2c-omap.c > +++ b/drivers/i2c/busses/i2c-omap.c > @@ -625,6 +625,7 @@ omap_i2c_xfer(struct i2c_adapter *adap, struct i2c_msg msgs[], int num) > if (IS_ERR_VALUE(r)) > goto out; > > + enable_irq(dev->irq); > r = omap_i2c_wait_for_bb(dev); > if (r < 0) > goto out; > @@ -654,6 +655,7 @@ omap_i2c_xfer(struct i2c_adapter *adap, struct i2c_msg msgs[], int num) > > omap_i2c_wait_for_bb(dev); > out: > + disable_irq(dev->irq); > pm_runtime_mark_last_busy(dev->dev); > pm_runtime_put_autosuspend(dev->dev); > return r; > @@ -1179,6 +1181,7 @@ omap_i2c_probe(struct platform_device *pdev) > goto err_unuse_clocks; > } > > + disable_irq(dev->irq); > adap = &dev->adapter; > i2c_set_adapdata(adap, dev); > adap->owner = THIS_MODULE; > -- > 1.7.5.4 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@xxxxxxxxxxxxxxxxxxx > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
