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

iio: adc: ad7173: fix compiling without gpiolib

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-testing 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 be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open.

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

From c553aa1b03719400a30d9387477190d4743fc1de Mon Sep 17 00:00:00 2001 From: David Lechner dlechner@baylibre.com Date: Tue, 22 Apr 2025 15:12:27 -0500 Subject: iio: adc: ad7173: fix compiling without gpiolib

Fix compiling the ad7173 driver when CONFIG_GPIOLIB is not set by selecting GPIOLIB to be always enabled and remove the #if.

Commit 031bdc8aee01 ("iio: adc: ad7173: add calibration support") placed unrelated code in the middle of the #if IS_ENABLED(CONFIG_GPIOLIB) block which caused the reported compile error.

However, later commit 7530ed2aaa3f ("iio: adc: ad7173: add openwire detection support for single conversions") makes use of the gpio regmap even when we aren't providing gpio controller support. So it makes more sense to always enable GPIOLIB rather than trying to make it optional.
