posix-timers: Make do_clock_gettime() static

Jiri Slaby · KAGA-KOKO · commit 221f9d9cdf42 · 2022-08-06T10:33:54.000+02:00
do_clock_gettime() is used only in posix-stubs.c, so make it static. It avoids a compiler warning too: time/posix-stubs.c:73:5: warning: no previous prototype for ‘do_clock_gettime’ [-Wmissing-prototypes] Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20220719085620.30567-1-jslaby@suse.cz
