Tests failed with A' * x when A is a CuSparseMatrixCSC{ComplexF32} or a CuSparseMatrixCSC{ComplexF64}. All tests passed with CuSparseMatrixCSR{...}.

The culprit should be mv! : https://github.com/JuliaGPU/CuArrays.jl/blob/master/src/sparse/wrappers.jl#L554-L584

The conjugate-transpose of a transposed complex matrix A is not A but conj(A), it's why tests failed with complex matrices.

I read the documentation of csrmv function and it seems that they forgot this corner case.
https://docs.nvidia.com/cuda/cusparse/index.html#csrmv

@maleadt, it's ready to be tested.

cuind variable is not used. I removed it.

What about:

[[DEPRECATED]] use cusparseSpMV() instead. The routine will be removed in the next major release

About the DEPRECATED csrmv, it concerned numerous functions in CUSPARSE module. 😟
