After adding some debug info I got:

************ register is 512
wm8962 0-001a: ASoC: error at soc_component_read_no_lock on wm8962.0-001a: -16

************ register is 515
wm8962 0-001a: ASoC: error at soc_component_read_no_lock on wm8962.0-001a: -16

Both register 512 and 515 do not exist as per the WM8962 datasheet, so
the driver should not try to access them, right?

This patch avoids reading from these unexisting registers, which makes
sense IMHO.

Do you have any other suggestions to avoid these errors?

Thanks
