This is a note to let you know that I've just added the patch titled rtc: mcp795: Add SPI ID table to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: rtc-mcp795-add-spi-id-table.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit af4af8964e857f1205dcd0b6a9e2c72635cefe4f Author: Mark Brown <broonie@xxxxxxxxxx> Date: Mon Sep 27 14:02:40 2021 +0100 rtc: mcp795: Add SPI ID table [ Upstream commit 3109151c47343c80300177ec7704e0757064efdc ] Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding an id_table listing the SPI IDs for everything.
