Subject: patch "counter: 104-quad-8: Fix Synapse action reported for Index signals" added to char-misc-linus
Date: Mon, 20 Mar 2023 13:57:17 +0100 [thread overview]
Message-ID: <167931703787245@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
counter: 104-quad-8: Fix Synapse action reported for Index signals
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.

Subject: counter: 104-quad-8: Fix Synapse action reported for Index signals
Signal 16 and higher represent the device's Index lines. The
priv->preset_enable array holds the device configuration for these Index
lines. The preset_enable configuration is active low on the device, so
invert the conditional check in quad8_action_read() to properly handle
the logical state of preset_enable.
