Subject: [PATCH] brcmfmac: treat NULL character in NVRAM as separator
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit

|
Platform NVRAM (stored on a flash partition) has entries separated by a
|
|
NULL (\0) char. Our parsing code switches from VALUE state to IDLE
|
|
whenever it meets a NULL (\0). When that happens our IDLE handler should
|
|
simply consume it and analyze whatever is placed ahead.
|
|
|
|
This fixes harmless warnings spamming debugging output:

[ 155.165624] brcmfmac: brcmf_nvram_handle_idle warning: ln=1:col=20: ignoring invalid character

|
