Subject: [PATCH] commands: i2c: Listen for CTRL-C when probing
Date: Tue, 15 Nov 2016 06:46:27 -0800	[thread overview]
Message-ID: <1479221187-13482-1-git-send-email-andrew.smirnov@gmail.com> (raw)

Allow I2C bus probing to be interrupted early by sending CTRL-C. This is
usefull when calling the tool without any arguments and one of the busses
is misconfigured (waiting for 100+ failures is pretty inconvenient).
