From 279b4cb7bc143643b6380a7198834f3bfbee7df7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 20 May 2015 13:59:54 +0200 Subject: [PATCH] brcmfmac: treat \0 as end of comment when parsing NVRAM MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This fixes brcmfmac dealing with NVRAM coming from platform e.g. from a flash MTD partition. In such cases entries are separated by \0 instead of \n which caused ignoring whole content after the first "comment". While platform NVRAM doesn't usually contain comments, we switch to COMMENT state after e.g. finding an unexpected char in key name.
