+Subject: [PATCH 4/5] HID: wacom: Correct NULL dereference on AES pen proximity
+
+The recent commit to fix a memory leak introduced an inadvertant NULL
+pointer dereference. The `wacom_wac->pen_fifo` variable was never
+intialized, resuling in a crash whenever functions tried to use it.
+Since the FIFO is only used by AES pens (to buffer events from pen
+proximity until the hardware reports the pen serial number) this would
+have been easily overlooked without testing an AES device.
+
+This patch converts `wacom_wac->pen_fifo` over to a pointer (since the
+call to `devres_alloc` allocates memory for us) and ensures that we assign
+it to point to the allocated and initalized `pen_fifo` before the function
+returns.
+
+Link: https://github.com/linuxwacom/input-wacom/issues/230
+Fixes: 37309f47e2f5 ("HID: wacom: Fix memory leakage caused by kfifo_alloc")
+CC: stable@vger.kernel.org # v4.19+
