Subject: [PATCH] Fix some minor inconsistencies in LAPACK(E)_[cz]gesvdq
For LAPACKE_cgesvdq, align datatype of `rwork` with lapacke.h and callsite
in LAPACKE_cgesvdq_work; both of the latter use `float* rwork`, so there's
no need to calculate with doubles that only get downcast anyway.
Similarly, make the signature of lapacke_zgesvdq_work consistent across
lapack.h (modified here), the fortran side and lapacke_zgesvdq_work, see:
