The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 54d394905c92b9ecc65c1f9b2692c8e10716d8e1 Mon Sep 17 00:00:00 2001 From: Javier Carrasco Date: Mon, 2 Dec 2024 20:18:44 +0100 Subject: iio: adc: ti-ads1119: fix sample size in scan struct for triggered buffer This device returns signed, 16-bit samples as stated in its datasheet (see 8.5.2 Data Format). That is in line with the scan_type definition for the IIO_VOLTAGE channel, but 'unsigned int' is being used to read and push the data to userspace. Given that the size of that type depends on the architecture (at least 2 bytes to store values up to 65535, but its actual size is often 4 bytes), use the 's16' type to provide the same structure in all cases.
