From: Guangguan Wang <redacted> [ Upstream commit 6912e724832c47bb381eb1bd1e483ec8df0d0f0f ] In the macro SMC_STAT_SERV_SUCC_INC, the smcd_version is used to determin whether to increase the v1 statistic or the v2 statistic. It is correct for SMCD. But for SMCR, smcr_version should be used. Signed-off-by: Guangguan Wang <redacted> Signed-off-by: David S.
