Ashutosh Dixit 82dc4afd7e misc: mic: Fix for double fetch security bug in VOP driver ...

The MIC VOP driver does two successive reads from user space to read a
variable length data structure. Kernel memory corruption can result if
the data structure changes between the two reads. This patch disallows
the chance of this happening.
