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

iio: xilinx-ams: Fix AMS_ALARM_THR_DIRECT_MASK

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-next 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 also be merged in the next major kernel release during the merge window.

If you have any questions about this process, please let me know.

From 1315cc2dbd5034f566e20ddce4d675cb9e6d4ddd Mon Sep 17 00:00:00 2001 From: Sean Anderson sean.anderson@linux.dev Date: Mon, 14 Jul 2025 20:30:58 -0400 Subject: iio: xilinx-ams: Fix AMS_ALARM_THR_DIRECT_MASK

AMS_ALARM_THR_DIRECT_MASK should be bit 0, not bit 1. This would cause hysteresis to be enabled with a lower threshold of -28C. The temperature alarm would never deassert even if the temperature dropped below the upper threshold.
