Subject: [PATCH] brcmfmac: increase buffer for obtaining firmware capabilities
|
|
|
|
When obtaining the firmware capability a buffer is provided of 512
|
|
bytes. However, if all features in firmware are supported the buffer
|
|
needs to be 565 bytes as otherwise truncated information is retrieved
|
|
from firmware. Increasing the buffer to 768 bytes on stack.
