When compiling wl12xx for x86, there was a warning complaining about the size of the buffer we were allocating in the stack: drivers/net/wireless/wl12xx/debugfs.c: In function 'driver_state_read': drivers/net/wireless/wl12xx/debugfs.c:380:1: warning: the frame size of 1040 bytes is larger than 1024 bytes To prevent this, allocate the buffer in the heap instead.
