Subject: [PATCH] cfi: init wait queue in chip struct
Date: Wed, 22 Feb 2006 14:29:21 -0000 [thread overview]
Message-ID: <43FC7532.6070404@soft.uni-linz.ac.at> (raw)
[-- Attachment #1: Type: text/plain, Size: 475 bytes --]
This patch fixes a kernel oops for Intel P30 flashes, where
the wait queue head was not initialized, which in turn caused
a crash at the first read operation.
