Charles Han df2f2d9199 Bluetooth: btbcm: Fix NULL deref in btbcm_get_board_name() 
[ Upstream commit b88655bc65 ]

devm_kstrdup() can return a NULL pointer on failure,but this
returned value in btbcm_get_board_name() is not checked.
Add NULL check in btbcm_get_board_name(), to handle kernel NULL
pointer dereference error.
