From 42f1d57f055064ed320d7292b95819dd81dda409 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 24 Sep 2020 17:21:00 +0200 Subject: [PATCH] m68k: change remaining timers to legacy_timer_tick There are nine more machines that each have their own timer interrupt calling the m68k timer_interrupt() function through an indirect pointer. This function is now the same as legacy_timer_tick, so just call that directly and select the corresponding Kconfig symbol.
