From 8deedfa2818c6854f91bf37fc36c80b4b7e73914 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Tue, 4 Oct 2022 02:41:13 +0700 Subject: gsm0502: use parentheses in GSM_TDMA_FN_{SUM,SUB} macros This makes it possible to pass expressions to the abovementioned macros without any side-effects. Strictly speaking, this is only necessary for argument 'b' of GSM_TDMA_FN_SUB, but let's also add them to GSM_TDMA_FN_SUM for consistency.
