This is a note to let you know that I've just added the patch titled HID: amd_sfh: Handle amd_sfh work buffer in PM ops to the 5.16-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: hid-amd_sfh-handle-amd_sfh-work-buffer-in-pm-ops.patch and it can be found in the queue-5.16 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 6d918c1951512c51592b13b70414c404ab36f3ae Author: Basavaraj Natikar <Basavaraj.Natikar@xxxxxxx> Date: Tue Feb 8 17:51:08 2022 +0530 HID: amd_sfh: Handle amd_sfh work buffer in PM ops [ Upstream commit 0cf74235f4403b760a37f77271d2ca3424001ff9 ] Since in the current amd_sfh design the sensor data is periodically obtained in the form of poll data, during the suspend/resume cycle, scheduling a delayed work adds no value. So, cancel the work and restart back during the suspend/resume cycle respectively.
