DSDF block - shouldn't x2c use x2 as input?

[dvorst]

Concerning the DSDF (RDDB) block

Shouldn't x2c (line 345) use x2 as input? Since x3c uses x3 as input (line 360) and x4c uses x4 as input (line 376)

MSRF-Net/model.py

Line 345 in 60e2373

x2c = Conv2D(filters=gc, kernel_size=3, strides=2,padding='same', bias=bias)(x1)

MSRF-Net/model.py

Line 360 in 60e2373

x3c = Conv2D(filters=gc, kernel_size=3, strides=2,padding='same', bias=bias)(x3)

x4c = Conv2D(filters=gc, kernel_size=3, strides=2,padding='same', bias=bias)(x4)
