From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx>
* Remove unneeded memset.
All the values in the PAPRD gain table are filled, so there
is no need to zero out the arrays.
* Use GFP_KERNEL in ar9003_paprd_create_curve
This is called from the PAPRD work, so the atomic variant
is not needed.
* Change return type of ar9003_paprd_setup_gain_table
