From ac01ce1410fc2c7b5f3af5e9c972e6a412eee54f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Wed, 29 Apr 2015 16:18:46 +0100 Subject: tracing: Make ftrace_print_array_seq compute buf_len MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The only caller to this function (__print_array) was getting it wrong by passing the array length instead of buffer length. As the element size was already being passed for other reasons it seems reasonable to push the calculation of buffer length into the function.
