efi_loader: Clean up efi_dp_append and efi_dp_concat 2024-01-13T17:17:47+00:00 Ilias Apalodimas ilias.apalodimas@linaro.org 2024-01-08T08:55:33+00:00 f19171c919e03c2590dce2f5026de2bf43203f7c Looking back at the initrd storing functionality, we introduced three functions, efi_dp_append_or_concatenate(), efi_dp_append/concat(). In hindsight we could have simplified that by a lot. First of all none of the functions append anything. They all allocate a new device path and concatenate the contents of two device paths in one. A boolean parameter controls the final device path -- if that's true an end node is injected between the two device paths. So let's rewrite this and make it a bit easier to read. Get rid of efi_dp_append(), efi_dp_concat() and rename efi_dp_append_or_concatenate() to efi_dp_concat(). This is far more intuitive and the only adjustment that is needed is an extra boolean argument on all callsites. Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
