From adf25df1be2e3843f786a2562202c7897bbd149d Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Tue, 27 Sep 2005 15:56:28 +0200 Subject: [ALSA] rtctimer: remove superfluous rtc_inc variable Modules: RTC timer driver The rtc_inc variable is never used outside the interrupt handler, and is always one where it matters, so we can just remove it.
