when you are breaking the line , make a point to align the next line with the open parenthesis.
like : 
-  mxs_lradc_reg_wrt(lradc, LRADC_DELAY_TRIGGER(0) | /* don't trigger ADC */
+  mxs_lradc_reg_wrt(lradc,
+          	     LRADC_DELAY_TRIGGER(0) | /* don't trigger ADC */

I have seen in many patches Greg commenting to resend the patch after aligning it.
so my opinion , even though it is optional , better to use it while sending a patch , so that no one can say about that.

happened to me in few of my initial patches. :)
