* leds: Use DEVICE_ATTR_{RW, RO, WO} macrosDwaipayan Ray2020-12-301-8/+8
| | | | | | | | | | | | | 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.
