From 50553c2c8145c3278668f385a71abbf79108e737 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 23 Nov 2011 09:34:50 +0300 Subject: [PATCH] ath6kl: use a larger buffer for debug output The return value of snprintf() is the number of bytes which would have been copied if there was enough space, but we want the number of bytes actually copied. The scnprintf() function does this. Also in theory, a %u can take take 10 digits so we may as well make the buffer larger as well.
