From e42386aedc2aa6ffac0885f4bbac318bb5819ea6 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 29 Aug 2008 19:25:01 -0300 Subject: dvb: fix I2C adapters name size From: Jean Delvare Some DVB drivers are incorrectly assuming that the size of i2c_adapter.name is I2C_NAME_SIZE. Here's a fix. Also change strncpy to strlcpy, as the former is error-prone (and was indeed incorrectly used.)
