Bluetooth: Use devm_kzalloc in bcm203x.c file.
devm_kzalloc() eliminates the need to free memory explicitly thereby saving some cleanup code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
