This is a note to let you know that I've just added the patch titled hwmon: (ltc2992) Set `can_sleep` flag for GPIO chip to the 6.1-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-ltc2992-set-can_sleep-flag-for-gpio-chip.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f8380212a2906a5f09033f4f36875cc36f5b78da Author: Lars-Peter Clausen <lars@xxxxxxxxxx> Date: Tue Mar 14 02:31:46 2023 -0700 hwmon: (ltc2992) Set `can_sleep` flag for GPIO chip [ Upstream commit ab00709310eedcd8dae0df1f66d332f9bc64c99e ] The ltc2992 drivers uses a mutex and 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. Fixes: 9ca26df1ba25 ("hwmon: (ltc2992) Add support for GPIOs.")
