+Subject: irqflags: Explicitly ignore lockdep_hrtimer_exit() argument
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit c1d11fc2c8320871b40730991071dd0a0b405bc8 upstream.
+
+When building with 'make W=1' but CONFIG_TRACE_IRQFLAGS=n, the
+unused argument to lockdep_hrtimer_exit() causes a warning:
+
+kernel/time/hrtimer.c:1655:14: error: variable 'expires_in_hardirq' set but not used [-Werror=unused-but-set-variable]
+
+This is intentional behavior, so add a cast to void to shut up the warning.
+
+Fixes: 73d20564e0dc ("hrtimer: Don't dereference the hrtimer pointer after the callback")
