2022-10-22leds: max8997: Don't error if there is no pdataPaul Cercueil1-6/+1
The driver works just fine if no platform data is supplied. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>
2020-12-30leds: Use DEVICE_ATTR_{RW, RO, WO} macrosDwaipayan Ray1-6/+6
Instead of open coding DEVICE_ATTR() defines, use the DEVICE_ATTR_RW(), DEVICE_ATTR_WO(), and DEVICE_ATTR_RO() macros. This required a few functions to be renamed, but the functionality itself is unchanged.

2018-07-03leds: max8997: use mode when calling max8997_led_set_modeColin Ian King1-1/+1
Variable mode is assigned to pdata->led_pdata->mode[led->id] and yet is not being used when calling function max8997_led_set_mode. Fix this by using mode when calling max8997_led_set_mode.

2016-03-14leds: max8997: Use devm_led_classdev_registerAmitoj Kaur Chawla1-13/+1
Switch to resource-managed function devm_led_classdev_register instead of led_classdev_register and remove unneeded led_classdev_unregister. Also, remove platform_set_drvdata in probe function and the remove function, max8997_led_remove as it is now has nothing to do. The Coccinelle semantic patch used to make this change is as follows: //<smpl> @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e; @@ probefn(struct platform_device *pdev, ...) { ... e = - led_classdev_register + devm_led_classdev_register (...); ... ?- led_classdev_unregister(...); ... } @remove depends on prb@ identifier platform.removefn; @@ removefn(...) { ... ?- led_classdev_unregister(...); ... } //</smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>

2012-07-24leds: max8997: Simplify max8997_led_set_mode implementationAxel Lin1-47/+13
It is not necessary to call max8997_update_reg() twice just for updating MAX8997_REG_LEN_CNTL register. With proper val and mask arguments to max8997_update_reg() call, this can be done in one max8997_update_reg() call. And then we can remove max8997_led_clear_mode() function.
