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/scsi/pcmcia/sym53c500_cs.c | 53 +++++++------------------------------- 1 file changed, 10 insertions(+), 43 deletions(-) (limited to 'drivers/scsi/pcmcia/sym53c500_cs.c') diff --git a/drivers/scsi/pcmcia/sym53c500_cs.c b/drivers/scsi/pcmcia/sym53c500_cs.c index 87d50b3..3a4dd6f 100644 --- a/drivers/scsi/pcmcia/sym53c500_cs.c +++ b/drivers/scsi/pcmcia/sym53c500_cs.c @@ -228,14 +228,6 @@ enum Phase { /* ================================================================== */ -/* -* Global (within this module) variables other than -* sym53c500_driver_template (the scsi_host_template). -*/ -static dev_info_t dev_info = "sym53c500_cs"; - -/* ================================================================== */ - static void chip_init(int io_port) { @@ -909,22 +901,6 @@ static int sym53c500_resume(struct pcmcia_device *dev) return 0; } -static int -SYM53C500_event(event_t event, int priority, event_callback_args_t *args) -{ - dev_link_t *link = args->client_data; - - DEBUG(1, "SYM53C500_event(0x%06x)\n", event); - - switch (event) { - case CS_EVENT_CARD_INSERTION: - link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; - SYM53C500_config(link); - break; - } - return 0; -} /* SYM53C500_event */ - static void SYM53C500_detach(struct pcmcia_device *p_dev) { @@ -939,20 +915,18 @@ SYM53C500_detach(struct pcmcia_device *p_dev) link->priv = NULL; } /* SYM53C500_detach */ -static dev_link_t * -SYM53C500_attach(void) +static int +SYM53C500_attach(struct pcmcia_device *p_dev) { struct scsi_info_t *info; - client_reg_t client_reg; dev_link_t *link; - int ret; DEBUG(0, "SYM53C500_attach()\n"); /* Create new SCSI device */ info = kmalloc(sizeof(*info), GFP_KERNEL); if (!info) - return NULL; + return -ENOMEM; memset(info, 0, sizeof(*info)); link = &info->link; link->priv = info; @@ -966,19 +940,13 @@ SYM53C500_attach(void) link->conf.IntType = INT_MEMORY_AND_IO; link->conf.Present = PRESENT_OPTION; - /* 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 != 0) { - cs_error(link->handle, RegisterClient, ret); - SYM53C500_detach(link->handle); - return NULL; - } + link->handle = p_dev; + p_dev->instance = link; - return link; + link->state |= DEV_PRESENT | DEV_CONFIG_PENDING; + SYM53C500_config(link); + + return 0; } /* SYM53C500_attach */ MODULE_AUTHOR("Bob Tracy "); @@ -998,8 +966,7 @@ static struct pcmcia_driver sym53c500_cs_driver = { .drv = { .name = "sym53c500_cs", }, - .attach = SYM53C500_attach, - .event = SYM53C500_event, + .probe = SYM53C500_attach, .remove = SYM53C500_detach, .id_table = sym53c500_ids, .suspend = sym53c500_suspend, -- cgit v1.1
