This is a note to let you know that I've just added the patch titled
iio: imu: adis16475: add spi_device_id table
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.
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 ee4d79055aeea27f1b8c42233cc0c90d0a8b5355 Mon Sep 17 00:00:00 2001 From: Nuno Sa nuno.sa@analog.com Date: Thu, 2 Nov 2023 13:52:58 +0100 Subject: iio: imu: adis16475: add spi_device_id table
This prevents the warning message "SPI driver has no spi_device_id for..." when registering the driver. More importantly, it makes sure that module autoloading works as spi relies on spi: modaliases and not of.
While at it, move the of_device_id table to it's natural place.
