From: David Lechner Date: Thu, 19 Jun 2025 15:24:22 +0000 (-0500) Subject: iio: adc: ad7380: fix adi,gain-milli property parsing X-Git-Tag: v6.16-rc7~10^2~16^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=24fa69894ea3f76ecb13d7160692ee574a912803;p=thirdparty%2Flinux.git iio: adc: ad7380: fix adi,gain-milli property parsing 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.
