Re: [ros-dev] [ros-diffs] [akhaldi] 53527: [WIN32K] * Remove some useless asserts considering cLockObj is DWORD.

[Alex Ionescu]

These asserts are not useless.

A DWORD can also underflow (due to a bug), hence the point of these ASSERTs
-- the only bug is that the ASSERT should cast to LONG.

Best regards,
Alex Ionescu
