[Emacs-diffs] master 534c33c: Fix return type of make_time.

[Philipp Stephani]

branch: master
commit 534c33cf375182c97291d2dd242f936df5953321
Author: Philipp Stephani <address@hidden>
Commit: Philipp Stephani <address@hidden>

    Fix return type of make_time.
    
    make_time is documented to return a (TICKS . HZ) pair, so we can’t use
    make_lisp_time.  Introduce a new conversion function instead.
    
    * src/emacs-module.c (module_make_time): Use timespec_to_lisp to
    correct return type.
    
    * src/timefns.c (timespec_to_lisp): New function.
    (make_lisp_time): Use it.
    
    * test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid):
    Check return type.
