From 9e9b3db1b2f725bacaf1b7e8708a0c78265bde97 Mon Sep 17 00:00:00 2001 From: "Milo(Woogyom) Kim" Date: Tue, 5 Feb 2013 19:06:27 +0900 Subject: leds-lp55xx: use lp55xx common led registration function LED class devices are registered in lp5521_register_leds() and lp5523_register_leds(). Two separate functions are merged into consolidated lp55xx function, lp55xx_register_leds(). Error handling fix: Unregistering LEDS are handled in lp55xx_register_leds() when LED registration failure occurs. So each driver error handler is changed to 'err_register_leds' Chip dependency: 'brightness_work_fn' and 'set_led_current' To make the structure abstract, both functions are configured in each driver. Those functions should be done by each driver because register control is chip-dependant work. lp55xx_init_led: skeleton Will be filled in next patch Signed-off-by: Milo(Woogyom) Kim Signed-off-by: Bryan Wu --- drivers/leds/leds-lp5521.c | 43 +++---------------------------------------- 1 file changed, 3 insertions(+), 40 deletions(-) (limited to 'drivers/leds/leds-lp5521.c') diff --git a/drivers/leds/leds-lp5521.c b/drivers/leds/leds-lp5521.c index dd4526e168fa..dc58f4106d09 100644 --- a/drivers/leds/leds-lp5521.c +++ b/drivers/leds/leds-lp5521.c @@ -738,44 +738,6 @@ static int lp5521_init_led(struct lp5521_led *led, return 0; } -static int lp5521_register_leds(struct lp5521_chip *chip) -{ - struct lp5521_platform_data *pdata = chip->pdata; - struct i2c_client *client = chip->client; - int i; - int led; - int ret; - - /* Initialize leds */ - chip->num_channels = pdata->num_channels; - chip->num_leds = 0; - led = 0; - for (i = 0; i < pdata->num_channels; i++) { - /* Do not initialize channels that are not connected */ - if (pdata->led_config[i].led_current == 0) - continue; - - ret = lp5521_init_led(&chip->leds[led], client, i, pdata); - if (ret) { - dev_err(&client->dev, "error initializing leds\n"); - return ret; - } - chip->num_leds++; - - chip->leds[led].id = led; - /* Set initial LED current */ - lp5521_set_led_current(chip, led, - chip->leds[led].led_current); - - INIT_WORK(&(chip->leds[led].brightness_work), - lp5521_led_brightness_work); - - led++; - } - - return 0; -} - static void lp5521_unregister_leds(struct lp5521_chip *chip) { int i; @@ -836,9 +798,9 @@ static int lp5521_probe(struct i2c_client *client, dev_info(&client->dev, "%s programmable led chip found\n", id->name); - ret = lp5521_register_leds(old_chip); + ret = lp55xx_register_leds(led, chip); if (ret) - goto fail2; + goto err_register_leds; ret = lp5521_register_sysfs(client); if (ret) { @@ -848,6 +810,7 @@ static int lp5521_probe(struct i2c_client *client, return ret; fail2: lp5521_unregister_leds(old_chip); +err_register_leds: lp55xx_deinit_device(chip); err_init: return ret; -- cgit v1.2.3
