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 be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From e2af60f5900c6ade53477b494ffb54690eee11f5 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 15 Nov 2022 14:23:23 +0100 Subject: iio: adc128s052: add proper .data members in adc128_of_match table Prior to commit bd5d54e4d49d ("iio: adc128s052: add ACPI _HID AANT1280"), the driver unconditionally used spi_get_device_id() to get the index into the adc128_config array. However, with that commit, OF-based boards now incorrectly treat all supported sensors as if they are an adc128s052, because all the .data members of the adc128_of_match table are implicitly 0. Our board, which has an adc122s021, thus exposes 8 channels whereas it really only has two.
