From f0a921518b7a016f0a9141933b0d766306394eff Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Wed, 26 May 2010 10:38:58 +0200 Subject: [PATCH] video: sm501.c: add weak default functions For boards using sm501/sm502 on PCI bus some driver functions normaly defined in the board code are not needed and empty. Provide weak default functions for them and do not enforce board code to define empty functions.
