Subject: [PATCH 04/22] [RESEND] time: make sysfs_get_uname() function visible in header

From: Arnd Bergmann <arnd@...db.de>

This function is defined globally in clocksource.c and used conditionally
in clockevent.c, which the declaration hidden when clockevent support
is disabled. This causes a harmless warning in the definition:

kernel/time/clocksource.c:1324:9: warning: no previous prototype for 'sysfs_get_uname' [-Wmissing-prototypes]
 1324 | ssize_t sysfs_get_uname(const char *buf, char *dst, size_t cnt)

Move the declaration out of the #ifdef so it is always visible.
