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 c9791a94384af07592d29504004d2255dbaf8663 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 5 Dec 2021 17:27:28 +0000 Subject: iio: adc: ti-adc081c: Partial revert of removal of ACPI IDs Unfortuanately a non standards compliant ACPI ID is known to be in the wild on some AAEON boards. Partly revert the removal of these IDs so that ADC081C will again work + add a comment to that affect for future reference. Whilst here use generic firmware properties rather than the ACPI specific handling previously found in this driver.
