From 0e72cc8b8d48ba05e705f432fb99aaa0ea6737c6 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 2 Nov 2010 00:22:23 -0300 Subject: [PATCH] [media] saa7164: make buffer smaller This isn't a runtime bug, it's just to make static checkers happy. In vidioc_querycap() we copy a saa7164_dev ->name driver array into a v4l2_capability -> driver array. The ->driver array is only 16 chars long so ->name also can't be more than 16 characters. The ->name gets set in v4l2_capability() and it always is less than 16 characters so we can easily make the buffer smaller.
