"No file to patch" when trying to apply patch

[Bjoern Kaufmann]

Hello,

I am currently trying to apply a patch on one of my components I want to build from sources using the dpkg bbclass:

 my-recipe_1.0.bb

inherit dpkg

SRC_URI = "git://some-repo.git;branch=master;protocol=ssh"

SRC_URI += "file://TPM-dictionary-attack-lock.patch"

SRCREV = "6fa1dbb543cb7147197c175bccd61e2bd443d36b"

my filetree looks like this:

my-recipe/

  my-recipe_1.0.bb

  files/

    TPM-dictionary-attack-lock.patch

The workdir after do_fetch, do_unpack etc. looks like the following:

But during do_patch when trying to apply the patch, it always gives me the error "No file to patch.":

stdout: Applying patch TPM-dictionary-attack-lock.patch
can't find file to patch at input line 15
Perhaps you used the wrong -p or --strip option?
