From 81906c357a37bd82ca041bbdde9c663ea656f300 Mon Sep 17 00:00:00 2001 From: Somya Anand Date: Wed, 11 Mar 2015 17:02:13 +0530 Subject: [PATCH] Staging: comedi: Use function setup_timer for combining initialization The function setup_timer combines the initialization of a timer with the initialization of the timer's function and data fields. So, this patch combines the multiline code for timer initialization using the function setup_timer. This issue is identified via coccinelle script. @@ expression E1, E2, E3; type T; @@ - init_timer(&E1); ...
