From 4440673a95e63ad888a41db596edaa0c55d3a332 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 24 May 2011 17:13:29 -0700 Subject: leds: provide helper to register "leds-gpio" devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This function makes a deep copy of the platform data to allow it to live in init memory. For a kernel that supports several machines and so includes the definition for several leds-gpio devices this saves quite some memory because all but one definition can be free'd after boot. As the function is used by arch code it must be builtin and so cannot go into leds-gpio.c.
