Hi Masaki,

The Alps touchpad (044E:1220) on Dell Precision 7530 causes IRQ storm after system suspend (S3).
Commit "HID: i2c-hid: Don't reset device upon system resumeâ which solves the same issue for other vendors, cause the issue on Alps touchpad.
So Iâd like to know the correct command Alps touchpad expects after system resume.

Also Cc Mario because this could relate to BIOS.
