    Subject[PATCH 4.4 51/78] kbuild: modpost: handle KBUILD_EXTRA_SYMBOLS only for external modules
    Date
    [ Upstream commit cb4819934a7f9b87876f11ed05b8624c0114551b ]

    KBUILD_EXTRA_SYMBOLS makes sense only when building external modules.
    Moreover, the modpost sets 'external_module' if the -e option is given.

    I replaced $(patsubst %, -e %,...) with simpler $(addprefix -e,...)
    while I was here.
