From: Christophe JAILLET christophe.jaillet@wanadoo.fr Date: Wed, 6 May 2020 05:52:06 +0200 Subject: [PATCH] iio: sca3000: Remove an erroneous 'get_device()'
This looks really unusual to have a 'get_device()' hidden in a 'dev_err()' call. Remove it.
While at it add a missing \n at the end of the message.
