[patch 23/39] [PATCH] cfi: init wait queue in chip struct

[Chris Wright]

-stable review patch.  If anyone has any objections, please let us know.
------------------

Fix 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.
