[PATCH 0/1] MR1852: winebus.sys: Declare a variable only when used

[Gerald Pfeifer (＠gerald)]

udev_add_device declares a variable (product) even when it is not used
on all platforms. Use the same condition for the declaration that already
guards the code.

Are there systems with hidraw backends which are not Linux? I'll approve this as the hidraw code isn't guarded consistently already but if it's not the case I think maybe we should probably guard all hidraw code and not just some parts.

I'm not sure. (One benefit of not simply guarding everything at once is broader compile time evaluation.)
