Subject: [PATCH 4/7] HPET: fix uninitialized variable in hpet_register()
Date: Tue, 04 Oct 2005 14:41:48 +0200 (MEST) [thread overview]
Message-ID: <20051004124148.23057.31736.schnuffi@turing> (raw)
In-Reply-To: <20051004124126.23057.75614.schnuffi@turing>
From: Clemens Ladisch <clemens@ladisch.de>
Clear the ht_opaque field in the hpet_register() function before
searching for a free timer to prevent the function from incorrectly
assuming that the search succeeded afterwards.
