This is a note to let you know that I've just added the patch titled
iio: imu: bno055: serdev requires REGMAP
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 35ec2d03b282a939949090bd8c39eb37a5856721 Mon Sep 17 00:00:00 2001 From: Randy Dunlap rdunlap@infradead.org Date: Wed, 10 Jan 2024 10:56:11 -0800 Subject: iio: imu: bno055: serdev requires REGMAP
There are a ton of build errors when REGMAP is not set, so select REGMAP to fix all of them.
Examples (not all of them):
