1 year ago I had the same error as well.
Just don't do that step: "Depending on the kernel version you're using, you also might need to change the following inside hci_ldisc.c:"
Leave as it is and continue the other steps. It works just fine.
Note: I have secure boot disabled and didn't do those secure boot steps as well.
Kernel: 5.4.0-150-generic Ubuntu 18.04.6
Need your help... I am trying to compile this patch for the kernel version 5.4-132 in Ubuntu.... and after making all proposed changes I got the following erro.
Could you please help me what is wrong and how to fix it.
Thanks in advance.
