dp_11_module_param_arr.diff
This is the 11st patch of 16 patches for devparam.
The unsigned int * @nump of module_param_array is changed back to unsigned int @num, and new sets of macros named module_param_arr*() are added. These new macros don't take the num argument. This change is made for two reasons
1. To be consistent with devparam macros. In devparam, we'll be using field name of struct elements, so we won't be able to use pointer argument. 2. It's more consistent with other moduleparam macros.
This patch only modifies moduleparam.h and doesn't modify the users of the modified macros. The next patch takes care of that. This and the next patch (dp_12_module_param_arr_apply.diff) are optional.
