Subject: [PATCH 06/14] i2c/i2c-nomadik: correct adapter timeout initialization
Date: Fri, 13 May 2011 12:29:46 +0200 [thread overview]
Message-ID: <1305282586-20693-1-git-send-email-linus.walleij@linaro.org> (raw)
From: Virupax Sadashivpetimath <virupax.sadashivpetimath-0IS4wlFg1OjSUeElwK9/Pw@public.gmane.org>
Correct the incorrect initialization of adapter timeout not to be
in milliseconds, as it needs to be done in jiffies.
