Date: Sun, 20 May 2018 08:50:35 +0200 From: Wolfram Sang <wsa@...-dreams.de> To: linux-i2c@...r.kernel.org Cc: Peter Rosin <peda@...ntia.se>, Wolfram Sang <wsa@...-dreams.de>, Mauro Carvalho Chehab <mchehab@...nel.org>, linux-media@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 4/7] media: em28xx: don't check number of messages in the driver Since commit 1eace8344c02 ("i2c: add param sanity check to i2c_transfer()"), the I2C core does this check now. We can remove it from drivers.
