A Sashiko review found two pre-existing issues in the ASUS ROG Ryujin
driver: missing HID report length validation and a race between completion
updates and reinitialization.

Reject undersized reports and serialize both paths with the existing
spinlock.

Tested on an ASUS ROG Ryujin III EVA using a DKMS-built module with 16,000
concurrent hwmon reads and 50 liquidctl status requests over hidraw. No
failures, timeouts, lock warnings, or HID errors were observed.

  hwmon: (asus_rog_ryujin) Validate HID report lengths
  hwmon: (asus_rog_ryujin) Synchronize HID command and report handling
