Jason Gerecke 179e8e47c0 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.
