From 56a6879866a8cb821bd8b154d0e37079e59799ff Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 15 Sep 2022 19:00:24 +0200 Subject: [PATCH] efi: libstub: drop pointless get_memory_map() call commit a675f3657ecfcbd7609f41615e954b2d96dc52d3 upstream. Currently, the non-x86 stub code calls get_memory_map() redundantly, given that the data it returns is never used anywhere. So drop the call.
