DO_PATCH

Patch a project under $(BUILD_WORK) with patches in $(BUILD_PATCH)

Arguments

This function applies patches/changes necessary for a project to function on a specific platform. The table below showcases all parameters required for the function to work

Index	Status	Description
1	Required	Folder name where patches are located; generally inside $(BUILD_PATCH)
2	Required	Folder name where patches should be applied to. This generally matches the name of the first argument, and the folder must exist in $(BUILD_WORK)
3	Optional	Extra arguments to patch. Usually this is -p1

Example

$(call DO_PATCH,youtube-dl,youtube-dl,-p1)

The example above looks for patches inside build_patch/youtube-dl and applies each patch (or diff) found to the project, youtube-dl (which can be found in build_work/youtube-dl).

Patches are generally a good idea when dealing with a big project that requires specific changes (that can't be put on the project's repository or isn't part of the project's upstream yet) for a specific platform.
