eCryptfs: NULL pointer dereference in ecryptfs_send_miscdev()
If data is NULL, msg_ctx->msg is set to NULL and then dereferenced
afterwards. ecryptfs_send_raw_message() is the only place that
ecryptfs_send_miscdev() is called with data being NULL, but the only
caller of that function (ecryptfs_process_helo()) is never called. In
short, there is currently no way to trigger the NULL pointer
dereference.
This patch removes the two unused functions and modifies
ecryptfs_send_miscdev() to remove the NULL dereferences.
