From 2f9e682d05e27fef1a78b4089cfde818ea109d25 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 28 Apr 2015 09:50:36 -0300 Subject: [PATCH] [media] cx18: avoid going past input/audio array As reported by smatch: drivers/media/pci/cx18/cx18-driver.c:807 cx18_init_struct2() error: buffer overflow 'cx->card->video_inputs' 6 <= 6 That happens because nof_inputs and nof_audio_inputs can be initialized as CX18_CARD_MAX_VIDEO_INPUTS, instead of CX18_CARD_MAX_VIDEO_INPUTS - 1.
