Decouple kzalloc from buffer creation, so that a managed allocation can be used: struct tpm_buf *buf __free(kfree) buf = kzalloc(TPM_BUFSIZE, GFP_KERNEL); if (!buf) return -ENOMEM; tpm_buf_init(buf, TPM_BUFSIZE); Alternatively, other allocations are also possible (static data, stack, etc) for example: u8 buf_data[512]; struct tpm_buf *buf = (struct tpm_buf *)buf_data; tpm_buf_init(buf, sizeof(buf_data)); This is achieved by embedding buffer's header inside the allocated blob, instead of having an outer wrapper.
