From 39de7d95f88d95a07f64b047c985fff31c006b5c Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 6 Jan 2016 08:05:52 -0200 Subject: [PATCH] [media] vpx3220: signedness bug in vpx3220_fp_read() The intent was to return -1 on error and that's what the callers expect but the current code returns USHRT_MAX instead.
