The same also occurs for linux-libre patches:

While executing meta-command:
ERROR:
  1. &formatted-message:
      format: "~a: patch not found\n"
      arguments: ("linux-libre-support-for-Pinebook-Pro.patch")

should allow us to rewrite the orgins in a more straight forward way,
hopefully eschewing this issue.
