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/net/wireless/spectrum_cs.c | 63 ++++++-------------------------------- 1 file changed, 10 insertions(+), 53 deletions(-) (limited to 'drivers/net/wireless/spectrum_cs.c') diff --git a/drivers/net/wireless/spectrum_cs.c b/drivers/net/wireless/spectrum_cs.c index 1933250dad1a..fee4be1ce810 100644 --- a/drivers/net/wireless/spectrum_cs.c +++ b/drivers/net/wireless/spectrum_cs.c @@ -56,17 +56,6 @@ static int ignore_cis_vcc; /* = 0 */ module_param(ignore_cis_vcc, int, 0); MODULE_PARM_DESC(ignore_cis_vcc, "Allow voltage mismatch between card and socket"); -/********************************************************************/ -/* Magic constants */ -/********************************************************************/ - -/* - * The dev_info variable is the "key" that is used to match up this - * device driver with appropriate cards, through the card - * configuration database. - */ -static dev_info_t dev_info = DRIVER_NAME; - /********************************************************************/ /* Data structures */ /********************************************************************/ @@ -82,8 +71,8 @@ struct orinoco_pccard { /* Function prototypes */ /********************************************************************/ +static void spectrum_cs_config(dev_link_t *link); static void spectrum_cs_release(dev_link_t *link); -static void spectrum_cs_detach(struct pcmcia_device *p_dev); /********************************************************************/ /* Firmware downloader */ @@ -594,19 +583,17 @@ spectrum_cs_hard_reset(struct orinoco_private *priv) * The dev_link structure is initialized, but we don't actually * configure the card at this point -- we wait until we receive a card * insertion event. */ -static dev_link_t * -spectrum_cs_attach(void) +static int +spectrum_cs_attach(struct pcmcia_device *p_dev) { struct net_device *dev; struct orinoco_private *priv; struct orinoco_pccard *card; dev_link_t *link; - client_reg_t client_reg; - int ret; dev = alloc_orinocodev(sizeof(*card), spectrum_cs_hard_reset); if (! dev) - return NULL; + return -ENOMEM; priv = netdev_priv(dev); card = priv->card; @@ -628,22 +615,13 @@ spectrum_cs_attach(void) link->conf.Attributes = 0; link->conf.IntType = INT_MEMORY_AND_IO; - /* Register with Card Services */ - /* FIXME: need a lock? */ - link->next = NULL; /* not needed */ + link->handle = p_dev; + p_dev->instance = link; - client_reg.dev_info = &dev_info; - client_reg.Version = 0x0210; /* FIXME: what does this mean? */ - client_reg.event_callback_args.client_data = link; + link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; + spectrum_cs_config(link); - ret = pcmcia_register_client(&link->handle, &client_reg); - if (ret != CS_SUCCESS) { - cs_error(link->handle, RegisterClient, ret); - spectrum_cs_detach(link->handle); - return NULL; - } - - return link; + return 0; } /* spectrum_cs_attach */ /* @@ -977,26 +955,6 @@ spectrum_cs_resume(struct pcmcia_device *p_dev) return 0; } -/* - * The card status event handler.
