From 8604affde9d4f52f04342d6a37c77d95fa167e7a Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 26 May 2005 14:55:34 +0200 Subject: [PATCH] convert IDE device drivers to driver-model * add ide_bus_match() and export ide_bus_type * split ide_remove_driver_from_hwgroup() out of ide_unregister() * move device cleanup from ide_unregister() to drive_release_dev() * convert ide_driver_t->name to driver->name * convert ide_driver_t->{attach,cleanup} to driver->{probe,remove} * remove ide_driver_t->busy as ide_bus_type->subsys.rwsem protects against concurrent ->{probe,remove} calls * make ide_{un}register_driver() void as it cannot fail now * use driver_{un}register() directly, remove ide_{un}register_driver() * use device_register() instead of ata_attach(), remove ata_attach() * add proc_print_driver() and ide_drivers_show(), remove ide_drivers_op * fix ide_replace_subdriver() and move it to ide-proc.c * remove ide_driver_t->drives, ide_drives and drives_lock * remove ide_driver_t->drivers, drivers and drivers_lock * remove ide_drive_t->driver and DRIVER() macro Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-floppy.c | 42 +++++++++++++++++------------------------- 1 file changed, 17 insertions(+), 25 deletions(-) (limited to 'drivers/ide/ide-floppy.c') diff --git a/drivers/ide/ide-floppy.c b/drivers/ide/ide-floppy.c index 36c0b74a4e4..c949e98df4b 100644 --- a/drivers/ide/ide-floppy.c +++ b/drivers/ide/ide-floppy.c @@ -1865,13 +1865,13 @@ static void idefloppy_setup (ide_drive_t *drive, idefloppy_floppy_t *floppy) idefloppy_add_settings(drive); } -static int idefloppy_cleanup (ide_drive_t *drive) +static int ide_floppy_remove(struct device *dev) { + ide_drive_t *drive = to_ide_device(dev); idefloppy_floppy_t *floppy = drive->driver_data; struct gendisk *g = floppy->disk; - if (ide_unregister_subdriver(drive)) - return 1; + ide_unregister_subdriver(drive, floppy->driver); del_gendisk(g); @@ -1916,26 +1916,24 @@ static ide_proc_entry_t idefloppy_proc[] = { #endif /* CONFIG_PROC_FS */ -static int idefloppy_attach(ide_drive_t *drive); +static int ide_floppy_probe(struct device *); -/* - * IDE subdriver functions, registered with ide.c - */ static ide_driver_t idefloppy_driver = { .owner = THIS_MODULE, - .name = "ide-floppy", + .gen_driver = { + .name = "ide-floppy", + .bus = &ide_bus_type, + .probe = ide_floppy_probe, + .remove = ide_floppy_remove, + }, .version = IDEFLOPPY_VERSION, .media = ide_floppy, - .busy = 0, .supports_dsc_overlap = 0, - .cleanup = idefloppy_cleanup, .do_request = idefloppy_do_request, .end_request = idefloppy_do_end_request, .error = __ide_error, .abort = __ide_abort, .proc = idefloppy_proc, - .attach = idefloppy_attach, - .drives = LIST_HEAD_INIT(idefloppy_driver.drives), }; static int idefloppy_open(struct inode *inode, struct file *filp) @@ -2122,8 +2120,9 @@ static struct block_device_operations idefloppy_ops = { .revalidate_disk= idefloppy_revalidate_disk }; -static int idefloppy_attach (ide_drive_t *drive) +static int ide_floppy_probe(struct device *dev) { + ide_drive_t *drive = to_ide_device(dev); idefloppy_floppy_t *floppy; struct gendisk *g; @@ -2152,10 +2151,7 @@ static int idefloppy_attach (ide_drive_t *drive) ide_init_disk(g, drive); - if (ide_register_subdriver(drive, &idefloppy_driver)) { - printk (KERN_ERR "ide-floppy: %s: Failed to register the driver with ide.c\n", drive->name); - goto out_put_disk; - } + ide_register_subdriver(drive, &idefloppy_driver); memset(floppy, 0, sizeof(*floppy)); @@ -2169,9 +2165,8 @@ static int idefloppy_attach (ide_drive_t *drive) drive->driver_data = floppy; - DRIVER(drive)->busy++; idefloppy_setup (drive, floppy); - DRIVER(drive)->busy--; + g->minors = 1 << PARTN_BITS; g->driverfs_dev = &drive->gendev; strcpy(g->devfs_name, drive->devfs_name); @@ -2181,19 +2176,17 @@ static int idefloppy_attach (ide_drive_t *drive) add_disk(g); return 0; -out_put_disk: - put_disk(g); out_free_floppy: kfree(floppy); failed: - return 1; + return -ENODEV; } MODULE_DESCRIPTION("ATAPI FLOPPY Driver"); static void __exit idefloppy_exit (void) { - ide_unregister_driver(&idefloppy_driver); + driver_unregister(&idefloppy_driver.gen_driver); } /* @@ -2202,8 +2195,7 @@ static void __exit idefloppy_exit (void) static int idefloppy_init (void) { printk("ide-floppy driver " IDEFLOPPY_VERSION "\n"); - ide_register_driver(&idefloppy_driver); - return 0; + return driver_register(&idefloppy_driver.gen_driver); } module_init(idefloppy_init); -- cgit v1.2.3-70-g09d2
