------------------------------------------------------
Subject: mtd: CHIPS: oops in cfi_amdstd_sync
From: Vijay Sampath <vsampath@xxxxxxxxx>
The files cfi_cmdset_0002.c and cfi_cmdset_0020.c do not initialize their
wait queues like is done in cfi_cmdset_0001.c. This causes an oops when
the wait queue is accessed. I have copied the code from cfi_cmdset_0001.c
that is pertinent to initialization of the wait queue.
