From: Mark Rutland Date: Wed, 16 Feb 2022 16:22:29 +0000 (+0000) Subject: linkage: remove SYM_FUNC_{START,END}_ALIAS() X-Git-Tag: v5.19~892^2~55^2~1 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=be9aea74400433e03c2a8b0260fc9ffe2495f698;p=mirror_ubuntu-kernels.git linkage: remove SYM_FUNC_{START,END}_ALIAS() Now that all aliases are defined using SYM_FUNC_ALIAS(), remove the old SYM_FUNC_{START,END}_ALIAS() macros. There should be no functional change as a result of this patch.
