  PLASMA_spotrs - Solves a system of linear equations A * X = B with a symmetric positive definite (or Hermitian positive definite in the complex case) matrix A using the Cholesky factorization A = U**T*U or A = L*L**T computed by PLASMA_spotrf. Parameters
  [in] | uplo | = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored.
  [in] | N | The order of the matrix A. N >= 0.
  [in] | NRHS | The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
  [in] | A | The triangular factor U or L from the Cholesky factorization A = U**T*U or A = L*L**T, computed by PLASMA_spotrf.
  [in] | LDA | The leading dimension of the array A. LDA >= max(1,N).
  [in,out] | B | On entry, the N-by-NRHS right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.
  [in] | LDB | The leading dimension of the array B. LDB >= max(1,N).
  Returns Return values
  PLASMA_SUCCESS | successful exit
  <0 | if -i, the i-th argument had an illegal value
