This is a note to let you know that I've just added the patch titled
iio: adc: ad7173: fix setting ODR in probe
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.

From 6fa908abd19cc35c205f343b79c67ff38dbc9b76 Mon Sep 17 00:00:00 2001 From: David Lechner dlechner@baylibre.com Date: Thu, 10 Jul 2025 15:43:40 -0500 Subject: iio: adc: ad7173: fix setting ODR in probe
Fix the setting of the ODR register value in the probe function for AD7177. The AD7177 chip has a different ODR value after reset than the other chips (0x7 vs. 0x0) and 0 is a reserved value on that chip.
The driver already has this information available in odr_start_value and uses it when checking valid values when writing to the sampling_frequency attribute, but failed to set the correct initial value in the probe function.
