Subject: [PATCH 4.9 037/218] brcmfmac: firmware: Allocate space for default boardrev in nvram
From: Hector Martin <marcan@...can.st>
commit d19d8e3ba256f81ea4a27209dbbd1f0a00ef1903 upstream.
If boardrev is missing from the NVRAM we add a default one, but this
might need more space in the output buffer than was allocated. Ensure
we have enough padding for this in the buffer.
Fixes: 46f2b38a91b0 ("brcmfmac: insert default boardrev in nvram data if missing")
