Subject: [PATCH] brcmfmac: treat \0 as end of comment when parsing NVRAM
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
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.
