Subject: [PATCH] qcacld-2.0: Use heap memory for station_info instead of stack
|
|
|
|
From kernel 3.19-rc4, size of struct station_info is around 600 bytes,
|
|
so stack frame size of such routine use this struct will easily
|
|
exceed 1024 bytes, the default value of stack frame size.
|
|
|
|
So use heap memory for this struct instead.
|
|
