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/bluetooth/btuart_cs.c | 46 +++++++++---------------------------------- 1 file changed, 9 insertions(+), 37 deletions(-) (limited to 'drivers/bluetooth/btuart_cs.c') diff --git a/drivers/bluetooth/btuart_cs.c b/drivers/bluetooth/btuart_cs.c index 7b04f89f7a7..7b4bff4cfa2 100644 --- a/drivers/bluetooth/btuart_cs.c +++ b/drivers/bluetooth/btuart_cs.c @@ -86,11 +86,7 @@ typedef struct btuart_info_t { static void btuart_config(dev_link_t *link); static void btuart_release(dev_link_t *link); -static int btuart_event(event_t event, int priority, event_callback_args_t *args); -static dev_info_t dev_info = "btuart_cs"; - -static dev_link_t *btuart_attach(void); static void btuart_detach(struct pcmcia_device *p_dev); @@ -580,17 +576,15 @@ static int btuart_close(btuart_info_t *info) return 0; } -static dev_link_t *btuart_attach(void) +static int btuart_attach(struct pcmcia_device *p_dev) { btuart_info_t *info; - client_reg_t client_reg; dev_link_t *link; - int ret; /* Create new info device */ info = kzalloc(sizeof(*info), GFP_KERNEL); if (!info) - return NULL; + return -ENOMEM; link = &info->link; link->priv = info; @@ -607,20 +601,13 @@ static dev_link_t *btuart_attach(void) link->conf.Vcc = 50; link->conf.IntType = INT_MEMORY_AND_IO; - /* Register with Card Services */ - link->next = NULL; - client_reg.dev_info = &dev_info; - client_reg.Version = 0x0210; - client_reg.event_callback_args.client_data = link; - - ret = pcmcia_register_client(&link->handle, &client_reg); - if (ret != CS_SUCCESS) { - cs_error(link->handle, RegisterClient, ret); - btuart_detach(link->handle); - return NULL; - } + link->handle = p_dev; + p_dev->instance = link; + + link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; + btuart_config(link); - return link; + return 0; } @@ -813,20 +800,6 @@ static int btuart_resume(struct pcmcia_device *dev) } -static int btuart_event(event_t event, int priority, event_callback_args_t *args) -{ - dev_link_t *link = args->client_data; - - switch (event) { - case CS_EVENT_CARD_INSERTION: - link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; - btuart_config(link); - break; - } - - return 0; -} - static struct pcmcia_device_id btuart_ids[] = { /* don't use this driver.
