* media: et8ek8: select V4L2_FWNODEArnd Bergmann2017-11-301-0/+1
| | | | | | | | | | | | | | | | | | | v4l2_async_register_subdev_sensor_common() is only provided when CONFIG_V4L2_FWNODE is enabled, otherwise we get a link failure: drivers/media/i2c/et8ek8/et8ek8_driver.o: In function `et8ek8_probe': et8ek8_driver.c:(.text+0x884): undefined reference to `v4l2_async_register_subdev_sensor_common' This adds a Kconfig 'select' statement like all the other users of this interface have.

* media: et8ek8: Decrease stack usageSakari Ailus2017-08-201-9/+17
| | | | | | | | | | The et8ek8 driver combines I²C register writes to a single array that it passes to i2c_transfer(). The maximum number of writes is 48 at once, decrease it to 8 and make more transfers if needed.

* [media] et8ek8: Export OF device ID as module aliasesJavier Martinez Canillas2017-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it. Before this patch: $ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias alias: i2c:et8ek8 After this patch: $ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias alias: i2c:et8ek8 alias: of:N*T*Ctoshiba,et8ek8C* alias: of:N*T*Ctoshiba,et8ek8 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
