Subject: MIPS: ath25: Check for kzalloc allocation failure

From: Colin Ian King <[email protected]>

commit 1b22b4b28fd5fbc51855219e3238b3ab81da8466 upstream.

Currently there is no null check on a failed allocation of board_data, and hence a null pointer dereference will occurr. Fix this by checking for the out of memory null pointer.
