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/dtl1_cs.c | 45 +++++++++------------------------------------ 1 file changed, 9 insertions(+), 36 deletions(-) (limited to 'drivers/bluetooth/dtl1_cs.c') diff --git a/drivers/bluetooth/dtl1_cs.c b/drivers/bluetooth/dtl1_cs.c index c39d4576cff..787c5eb9950 100644 --- a/drivers/bluetooth/dtl1_cs.c +++ b/drivers/bluetooth/dtl1_cs.c @@ -89,11 +89,7 @@ typedef struct dtl1_info_t { static void dtl1_config(dev_link_t *link); static void dtl1_release(dev_link_t *link); -static int dtl1_event(event_t event, int priority, event_callback_args_t *args); -static dev_info_t dev_info = "dtl1_cs"; - -static dev_link_t *dtl1_attach(void); static void dtl1_detach(struct pcmcia_device *p_dev); @@ -559,17 +555,15 @@ static int dtl1_close(dtl1_info_t *info) return 0; } -static dev_link_t *dtl1_attach(void) +static int dtl1_attach(struct pcmcia_device *p_dev) { dtl1_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; @@ -586,20 +580,13 @@ static dev_link_t *dtl1_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); - dtl1_detach(link->handle); - return NULL; - } + link->handle = p_dev; + p_dev->instance = link; - return link; + link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; + dtl1_config(link); + + return 0; } @@ -764,19 +751,6 @@ static int dtl1_resume(struct pcmcia_device *dev) return 0; } -static int dtl1_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; - dtl1_config(link); - break; - } - - return 0; -} static struct pcmcia_device_id dtl1_ids[] = { PCMCIA_DEVICE_PROD_ID12("Nokia Mobile Phones", "DTL-1", 0xe1bfdd64, 0xe168480d), @@ -790,8 +764,7 @@ static struct pcmcia_driver dtl1_driver = { .drv = { .name = "dtl1_cs", }, - .attach = dtl1_attach, - .event = dtl1_event, + .probe = dtl1_attach, .remove = dtl1_detach, .id_table = dtl1_ids, .suspend = dtl1_suspend, -- cgit v1.2.3
