From 081d868faeb7acdd655c28607f84e797240bd035 Mon Sep 17 00:00:00 2001 From: David Ellingsworth Date: Mon, 13 Oct 2008 17:54:52 -0300 Subject: V4L/DVB (9193): stk-webcam: minor cleanup This patch: 1) removes the unnecessary kref.h include file 2) removes unnecessary pointer validation from read and poll routines. (Neither poll nor read may be called unless a call to open succeeds. A successful call to open will always set the file private_data pointer. Verifying that it is not null is therefore unnecessary. The associated release and mmap calls currently ignore this check.) 3) adds a space to syslog output. 4) removes an unused function prototype.
