Hello,

I am simulating defect movement in a 2D colloid crystal system. I using a hybrid potential of yukawa/colloid and colloid. When I run it, I get the following error message.

```
ERROR: Pair coeff for hybrid has invalid style (src/pair_hybrid_overlay.cpp:63)
Last command: pair_coeff 1 1 yukawa/colloid ${A} ${rcut}
```

Are there any limitations on running yukawa/colloid and colloid as hybrid pair_styles on gpu. Is there a way to make it work?

Below is my input script.

```
package gpu 1
dimension 2
boundary p p p
atom_style sphere
units micro
# General model information
variable nx equal 16 # number of cells in x direction
variable ny equal 8 # number of cells in y direction
# Create Atoms
variable alat_init equal 1.1
lattice hex ${alat_init}

create_box 1 box
create_atoms 1 box
variable xint equal 0.5*${alat_init}
variable yint equal ${alat_init}*sqrt(3.0)/4.0
create_atoms 1 single ${xint} ${yint} 0.0
# Define Yukawa/Colloid and Colloid parameters
variable rcut equal ${alat_init}*sqrt(3.0)
variable A equal 8.1532e-4
variable kappa equal 1.0/(0.39)
pair_style hybrid/overlay yukawa/colloid/gpu ${kappa} ${rcut} colloid/gpu ${rcut}
pair_coeff 1 1 yukawa/colloid ${A} ${rcut}

```

Thank you,
