Default suggested by CellWise Android example code. I'll add a comment
explaining that.

This helper translates the memory write size. An u8 * is passed in while
regmap_read takes an unsigned int *. I'll drop it and just use an
unsigned int in the first place though.

Not really, or can it? Registers on the cw2015 are a wild mix of single
bytes and words. There does not seem to be a per register override for
reg_/val_bits.

I'll fix all style issues I find.

Will replace that with cancel_delayed_work_sync.
