[PATCH] kernel-doc: parse DECLARE_KFIFO_PTR()

[Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxxxxx>]

On media, we now have an struct declared with:

struct lirc_fh {
        struct list_head list;
        struct rc_dev *rc;
        int                             carrier_low;
        bool                            send_timeout_reports;
        DECLARE_KFIFO_PTR(rawir, unsigned int);
        DECLARE_KFIFO_PTR(scancodes, struct lirc_scancode);
        wait_queue_head_t               wait_poll;
        u8                              send_mode;
        u8                              rec_mode;
};

Currently, it produces the following error:

	./include/media/rc-core.h:96: warning: No description found for parameter 'int'
	./include/media/rc-core.h:96: warning: No description found for parameter 'lirc_scancode'
	./include/media/rc-core.h:96: warning: Excess struct member 'rawir' description in 'lirc_fh'
	./include/media/rc-core.h:96: warning: Excess struct member 'scancodes' description in 'lirc_fh'

So, teach kernel-doc how to parse a DECLARE_KFIFO_PTR();

While here, relax at the past DECLARE_foo() macros,
accepting a random number of spaces after comma.
