Subject: dl: Fix grub_dl_is_persistent() for emu
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cf5e52fa85ddabe919d30a5763690d2c6c48d1b8;p=thirdparty%2Fgrub.git

dl: Fix grub_dl_is_persistent() for emu

When attempting to build grub-emu the compilation failed with the
following error message:

  include/grub/dl.h: In function ‘grub_dl_is_persistent’:
  include/grub/dl.h:262:1: error: no return statement in function returning non-void [-Werror=return-type]

To avoid the error make the function always return 0.

Fixes: ba8eadde6be1 (dl: Provide a fake grub_dl_set_persistent() and grub_dl_is_persistent() for the emu target)
