Subject: staging: comedi: addi_apci_3501: board does not have analog inputs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e54ae8f6d4920a6734b909a44a601e0d722a84ac;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: comedi: addi_apci_3501: board does not have analog inputs

The board supported by this driver does not have analog inputs. Remove
the subdevice init for it.

Since the devpriv->s_EeParameters for the analog input subdevice are
not used, remove the initialization of them also.
