[PATCH] leds: Use DEVICE_ATTR_{RW, RO, WO} macros
From: Dwaipayan Ray
Date: Sat Dec 12 2020 - 14:57:47 EST
Instead of open coding DEVICE_ATTR() defines, use the
DEVICE_ATTR_RW(), DEVICE_ATTR_WO(), and DEVICE_ATTR_RO()
macros intead.
This required a few functions to be renamed, but the functionality
itself is unchanged.
Note that this is compile tested only.
