From c4fd07cd5e7ecd18aacd295d4de7bb309c74f601 Mon Sep 17 00:00:00 2001 From: James Morse Date: Tue, 17 Jan 2023 15:16:32 +0000 Subject: [PATCH] ia64: fix build error due to switch case label appearing next to declaration MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 6f28a2613497fc587e347afa99fa2c52230678a7 upstream. Since commit aa06a9bd8533 ("ia64: fix clock_getres(CLOCK_MONOTONIC) to report ITC frequency"), gcc 10.1.0 fails to build ia64 with the gnomic: | ../arch/ia64/kernel/sys_ia64.c: In function 'ia64_clock_getres': | ../arch/ia64/kernel/sys_ia64.c:189:3: error: a label can only be part of a statement and a declaration is not a statement | 189 | s64 tick_ns = DIV_ROUND_UP(NSEC_PER_SEC, local_cpu_data->itc_freq); This line appears immediately after a case label in a switch. Move the declarations out of the case, to the top of the function.
