[STABLE v5.15 0/2] HID: wacom: Fix Use-After-Free vulnerabilities in Wacom pad handling

[Lee Jones <lee@kernel.org>]

Backport the remaining two Wacom Use-After-Free fixes to v5.15.y, on top
of the five Wacom sibling-lifecycle and SW_MUTE_DEVICE patches already
queued in stable-queue (queue-5.15).

Both patches have been adapted to the queued res_wacom variable naming
in wacom_remove_shared_data() and use explicit locking calls for
-std=gnu89 compatibility.
