This is a note to let you know that I've just added the patch titled

Revert "comedi: add HAS_IOPORT dependencies"

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 98a15816636044f25be4644db2a3e09fad68aaf7 Mon Sep 17 00:00:00 2001 From: Ian Abbott abbotti@mev.co.uk Date: Tue, 5 Sep 2023 10:09:22 +0100 Subject: Revert "comedi: add HAS_IOPORT dependencies"

This reverts commit b5c75b68b7ded84d4c82118974ce3975a4dcaa74.

The commit makes it impossible to select configuration options that depend on COMEDI_8254, COMEDI_DAS08, COMEDI_NI_LABPC, or COMEDI_AMPLC_DIO200 options due to changing 'select' directives to 'depends on' directives and there being no other way to select those codependent configuration options.
