Riedl Date: Sat, 27 Feb 2021 01:12:53 +0000 (-0600) Subject: powerpc: Reference parameter in MSR_TM_ACTIVE() macro X-Git-Tag: v5.13-rc1~90^2~263 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1a130b67c682be9842f188f593c2080786de4204;p=thirdparty%2Flinux.git powerpc: Reference parameter in MSR_TM_ACTIVE() macro Unlike the other MSR_TM_* macros, MSR_TM_ACTIVE does not reference or use its parameter unless CONFIG_PPC_TRANSACTIONAL_MEM is defined. This causes an 'unused variable' compile warning unless the variable is also guarded with CONFIG_PPC_TRANSACTIONAL_MEM. Reference but do nothing with the argument in the macro to avoid a potential compile warning. Signed-off-by: Christopher M.
