[PATCH 1/5] HID: wacom: Use hdev->product in wacom_setup_touch_input_capabilities
From: Lee Jones
Date: Tue Aug 25 2026 - 13:09:23 EST
Replace the lookup-dependent 'wacom_wac->shared->touch->product' references
with 'hdev->product' inside wacom_setup_touch_input_capabilities() since
'hdev' is already available (via container_of) and represents the touch
device itself.
