Hi!

Allow the full scale current to be configured at init.
Valid rangles are 5mA->29.8mA.

No need to move ctrl_brt_pointer... to keep order consistent with docs.

OK I will reset the patches and get rid of that change.  I think this got moved when I applied the v1 patch.


+ fs_current_val = led->full_scale_current - LM3532_FS_CURR_MIN /
+ LM3532_FS_CURR_STEP;
The computation is wrong ... needs () AFAICT.

Hmm. Doesn't order of operations take precedence?

I will add the () unless checkpatch cribs about them
