6.15-stable review patch. If anyone has any objections, please let me know.

commit 24fa69894ea3f76ecb13d7160692ee574a912803 upstream.
Change the data type of the "adi,gain-milli" property from u32 to u16. The devicetree binding specifies it as uint16, so we need to read it as such to avoid an -EOVERFLOW error when parsing the property.
