------------------------------------------------------ From: James Morse james.morse@arm.com Subject: ia64: fix build error due to switch case label appearing next to declaration Date: Tue, 17 Jan 2023 15:16:32 +0000

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.
