Subject: ipack/devices/ipoctal: add missing rx_enable = 1
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2910fe2a7d0dc0d01944110e462045441ba0856f;p=linux-beck.git

ipack/devices/ipoctal: add missing rx_enable = 1

There was a bug in the code when managing a GE IP-OCTAL-485 board. The RX would
be enabled but we have a wrong state in the rx_enable flag.

Then, if the user changes the terminal settings, RX would not be enabled again.
