KEYS: trusted: Fix missing null return from kzalloc call
The kzalloc call can return null with the GFP_KERNEL flag so add a null check and exit via a new error exit label. Use the same exit error label for another error path too. Addresses-Coverity: ("Dereference null return value") Fixes: 830027e2cb55 ("KEYS: trusted: Add generic trusted keys framework") Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Sumit Garg <sumit.garg@linaro.org> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>
