From 2515d8437bf3a4415d3354d01e37f07d922250e2 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 12 Nov 2012 14:34:25 +0000 Subject: [PATCH] i2c: Use __weak instead of __attribute__((weak, alias)) Use __weak from linux/compiler.h instead of __attribute__((weak, alias)) to define overridable function. This patch is intended as a cleanup patch to bring some consistency into the code.
