Subject: kunit: tool: simplify creating LinuxSourceTreeOperations
X-Git-Tag: v6.1-rc5~750^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8c278d97ad721442692e610007494e8e18cc0288;p=platform%2Fkernel%2Flinux-starfive.git

kunit: tool: simplify creating LinuxSourceTreeOperations

Drop get_source_tree_ops() and just call what used to be
get_source_tree_ops_from_qemu_config() in both cases.

Also rename the functions to have shorter names and add a "_" prefix to
note they're not meant to be used outside this function.
