    Subject[PATCH 5.15 016/196] HID: amd_sfh: Increase sensor command timeout
    Date
    From: Basavaraj Natikar <Basavaraj.Natikar@amd.com>

    commit a7072c01c3ac3ae6ecd08fa7b43431cfc8ed331f upstream.

    HPD sensors take more time to initialize. Hence increasing sensor
    command timeout to get response with status within a max timeout.

    Fixes: 173709f50e98 ("HID: amd_sfh: Add command response to check command status")
