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 89944d88f8795c6c89b9514cb365998145511cd4 Mon Sep 17 00:00:00 2001 From: David Lechner Date: Mon, 28 Apr 2025 20:55:34 -0500 Subject: iio: adc: ad7606_spi: fix reg write value mask Fix incorrect value mask for register write. Register values are 8-bit, not 9. If this function was called with a value > 0xFF and an even addr, it would cause writing to the next register.
