From f8cfa618dccbdc6dab5297f75779566a388a98fd Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 14 Nov 2005 21:25:51 +0100 Subject: [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski --- drivers/char/pcmcia/synclink_cs.c | 49 +++++++-------------------------------- 1 file changed, 8 insertions(+), 41 deletions(-) (limited to 'drivers/char/pcmcia/synclink_cs.c') diff --git a/drivers/char/pcmcia/synclink_cs.c b/drivers/char/pcmcia/synclink_cs.c index dc38b1d0a72..cf45b100eff 100644 --- a/drivers/char/pcmcia/synclink_cs.c +++ b/drivers/char/pcmcia/synclink_cs.c @@ -486,13 +486,8 @@ static void mgslpc_wait_until_sent(struct tty_struct *tty, int timeout); static void mgslpc_config(dev_link_t *link); static void mgslpc_release(u_long arg); -static int mgslpc_event(event_t event, int priority, - event_callback_args_t *args); -static dev_link_t *mgslpc_attach(void); static void mgslpc_detach(struct pcmcia_device *p_dev); -static dev_info_t dev_info = "synclink_cs"; - /* * 1st function defined in .text section.
