From 1a2a99c69eaea30da25dede555a3d70d7a412ae2 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 5 Dec 2013 11:26:24 +0200 Subject: [PATCH] gpiolib: introduce chip_* to print with chip->label prefix In several places we are printing messages with prefix based on chip->label. Introduced macros help us to do this easier and in uniform way.
