Subject: [PATCH v2 21/31] s390/char/sclp: Use separate static data field with with static timer
Date: Wed, 20 Sep 2017 16:27:45 -0700 [thread overview]
Message-ID: <1505950075-50223-22-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1505950075-50223-1-git-send-email-keescook@chromium.org>
In preparation for changing the timer callback argument to the timer
pointer, move to a separate static data variable.
