Date: Tue, 30 Jul 2019 19:55:54 +0200 From: Wolfram Sang <wsa+renesas@...g-engineering.com> To: linux-i2c@...r.kernel.org Cc: Sean Young <sean@...s.org>, linux-media@...r.kernel.org, Wolfram Sang <wsa+renesas@...g-engineering.com>, Mauro Carvalho Chehab <mchehab@...nel.org>, linux-kernel@...r.kernel.org Subject: [PATCH v2 1/2] media: ir-kbd-i2c: convert to i2c_new_dummy_device() Convert this driver to use the new i2c_new_dummy_device() call and bail out if the dummy device cannot be registered to make failure more visible to the user.
