[edk2-devel] [PATCH v2 2/3] MdeModulePkg/UhciPei: Initialize the variable RequestMap

[Zhang, Shenglei]

RequestMap is used but not Initialized.
RequestMap is called by UhciMapUserRequest, in which RequestMap(Map)
is called by IoMmuMap, and is finally called by IoMmu->Map.
We can not assume RequestMap is given an initial value at any step.
