Subject: [PATCH] cfi: init wait queue in chip struct
Date: Wed, 22 Feb 2006 15:41:31 +0100 [thread overview]
Message-ID: <43FC781B.5030608@researchstudios.at> (raw)
This patch fixes a kernel oops for Intel P30 flashes, where
the wait queue head was not initialized for the flchip struct, which
in turn caused a crash at the first read operation.
