This is a note to let you know that I've just added the patch titled hwmon: (adm1266) Set `can_sleep` flag for GPIO chip to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: hwmon-adm1266-set-can_sleep-flag-for-gpio-chip.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 92918ab19bb03b44f45d1f5c74bfb9d39cf26848 Author: Lars-Peter Clausen <lars@xxxxxxxxxx> Date: Tue Mar 14 02:31:45 2023 -0700 hwmon: (adm1266) Set `can_sleep` flag for GPIO chip [ Upstream commit a5bb73b3f5db1a4e91402ad132b59b13d2651ed9 ] The adm1266 driver uses I2C bus access in its GPIO chip `set` and `get` implementation. This means these functions can sleep and the GPIO chip should set the `can_sleep` property to true. This will ensure that a warning is printed when trying to set or get the GPIO value from a context that potentially can't sleep.
