This patch aims to replace the of_property_read_u32 for reading
the amstaos,cover-comp-gain property with device_property_read_u32
Thanks and Regards,

Should keep this stuff about the --- to just the patch description as that
will end up in the git log when I pick up the patch. You can add
any extra stuff as notes as long as it is after the --- below.

A really minor comment below, but I'd like a couple of header tweaks
to be part of this patch as well to reflect that we are removing the
explicit use of of_* in this driver (which is great btw!)
At the moment we are getting the following headers only via indirect
includes. As we are using things directly defined in them please add
#include <linux/property.h> (for the device_property_read*)
#include <linux/mod_devicetable.h> (for the of_device_id table)
Thanks,
Jonathan

Hmm. This is a small change in logic. I'm not sure it really matters,
but should have been called out explicitly in the patch description.
