From 2df59b2bd4bf0dee0884fc774591eedd232141e6 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 4 Apr 2022 14:43:51 -0400 Subject: [PATCH] Remove duplication of table_compute_checksum function It seems like there was some merge error when first cleaning up and sharing this function. We have both an inline version of the function in include/tables_csum.h and a non-inline version in lib/tables_csum.c. Rework things so that we only have the non-inline version (due to number of calls, we should not inline this).
