It might be worth noting that the network subsystem maintainer prefers
this style as well. So most networking patches should probably use it.
The exception would be files which already use the other style.
You should also be aware of the implications of this style: You have to
modify all three lines if you change anything on the first line causing
the position of the starting '(' to change. I.e., a patch like this is
not acceptable:
-pdata->urbdata = usb_alloc_coherent(pdata->udev, ACD_URB_BUFFER_LEN,
+p->urbdata = usb_alloc_coherent(pdata->udev, ACD_URB_BUFFER_LEN,
GFP_KERNEL,
&pdata->urb->transfer_dma);
It needs to be
-pdata->urbdata = usb_alloc_coherent(pdata->udev, ACD_URB_BUFFER_LEN,
- GFP_KERNEL,
- &pdata->urb->transfer_dma);
+p->urbdata = usb_alloc_coherent(pdata->udev, ACD_URB_BUFFER_LEN,
+ GFP_KERNEL,
+ &pdata->urb->transfer_dma);
