kernel-doc: parse DECLARE_KFIFO and DECLARE_KFIFO_PTR()
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; }; gpiolib.c has a similar declaration with DECLARE_KFIFO(). Currently, those produce 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' ../drivers/gpio/gpiolib.c:601: warning: No description found for parameter '16' ../drivers/gpio/gpiolib.c:601: warning: Excess struct member 'events' description in 'lineevent_state' So, teach kernel-doc how to parse DECLARE_KFIFO() and DECLARE_KFIFO_PTR(). While here, relax at the past DECLARE_foo() macros, accepting a random number of spaces after comma. The addition of DECLARE_KFIFO() was Suggested-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Tested-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
