i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

There are only few users, so this patch converts the I2C core and all users in one go.

media: i2c: adv748x: Export I2C device table entries as module aliases The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, and the driver is only exporting the OF ID table entries as module aliases. So if the driver is built as module, autoload won't work since udev/kmod won't be able to match the registered OF device with its driver module. Before this patch: $ modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias alias: of:N*T*Cadi,adv7482C* alias: of:N*T*Cadi,adv7482 alias: of:N*T*Cadi,adv7481C* alias: of:N*T*Cadi,adv7481 After this patch: modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias alias: of:N*T*Cadi,adv7482C* alias: of:N*T*Cadi,adv7482 alias: of:N*T*Cadi,adv7481C* alias: of:N*T*Cadi,adv7481 alias: i2c:adv7482 alias: i2c:adv7481 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

media: i2c: adv748x: add adv748x driver Provide support for the ADV7481 and ADV7482. The driver is modelled with 4 subdevices to allow simultaneous streaming from the AFE (Analog front end) and HDMI inputs though two CSI TX entities. The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked to the TXB CSI bus. The driver is based on a prototype by Koji Matsuoka in the Renesas BSP, and an earlier rework by Niklas Söderlund.
