tbsv solves

     Ax = b or ATx = b or AHx = b,

where x and b are vectors and A is a banded triangular matrix.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.

@param[in]
uplo    [rocblas_fill]
        rocblas_fill_upper:  A is an upper triangular matrix.
        rocblas_fill_lower:  A is a  lower triangular matrix.

@param[in]
transA     [rocblas_operation]
           rocblas_operation_none: Solves Ax = b
           rocblas_operation_transpose: Solves ATx = b
           rocblas_operation_conjugate_transpose: Solves AHx = b

@param[in]
diag    [rocblas_diagonal]
        rocblas_diagonal_unit:     A is assumed to be unit triangular (i.e. the diagonal elements
                                   of A are not used in computations).
        rocblas_diagonal_non_unit: A is not assumed to be unit triangular.

@param[in]
n         [rocblas_int]
          n specifies the number of rows of b. n >= 0.
@param[in]
k         [rocblas_int]
          if(uplo == rocblas_fill_upper)
            k specifies the number of super-diagonals of A.
          if(uplo == rocblas_fill_lower)
            k specifies the number of sub-diagonals of A.
          k >= 0.

@param[in]
A         device pointer storing the matrix A in banded format.

@param[in]
lda       [rocblas_int]
          specifies the leading dimension of A.
          lda >= (k + 1).

@param[inout]
x         device pointer storing input vector b. Overwritten by the output vector x.

@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of x.
