Subject: patman: Move warning collection to a function
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b5cc39905343312d1b7064ede72561394049be21;p=u-boot.git

patman: Move warning collection to a function

Add a new function in PatchStream to collect the warnings generated while
parsing the stream. This will allow us to adjust the logic, such as
dealing with per-commit warnings.

Two of the warnings are in fact internal errors, so change them to raise
and exception.
