Subject: [PATCH 04/37] it913x: avoid division by zero on error case
Date: Thu,  4 Sep 2014 05:36:12 +0300	[thread overview]
Message-ID: <1409798205-25645-4-git-send-email-crope@iki.fi> (raw)
In-Reply-To: <1409798205-25645-1-git-send-email-crope@iki.fi>

Error on init leaves some internal divisor zero, which causes oops
later. Fix it by populating divisors even it fails.
