From 4514108c5b8088ab4a72ba27eb093882d76619cf Mon Sep 17 00:00:00 2001 From: Samuel Iglesias Gonsalvez Date: Thu, 13 Sep 2012 12:32:22 +0200 Subject: [PATCH] Staging: ipack/devices/ipoctal: acknowledge BREAK condition. Clear the BREAK flag from the ISR register. Doing that, we avoid to read the same condition for the next character received.
