I was trying to use LinearMap with a CuArray, and this issue blocked me.

Thanks, this LGTM. While you're at it, could you please also replace the two Array constructors in kronecker.jl, lines 109-110?

[kose-y]

Sure.

[dkarrasch]

Thanks once more. Now I realize that we may actually not need the T = eltype(y)/Ty = eltype(y) stuff (in both cases), since the default is y's eltype anyway. Could you please remove them?

[dkarrasch]

Many thanks for your contribution. I'll release this soonish after #72 is merged as v2.6.

[Jutho]

Much better indeed, thanks.
