It differs between i2c drivers and as such can be confusing. To see which chip variants are supported you can look in the i2c driver code for the i2c_device_id table. This lists all the possibilities. +There are two more helper functions: + +v4l2_i2c_new_subdev_cfg: this function adds new irq and platform_data +arguments and has both 'addr' and 'probed_addrs' arguments: if addr is not +0 then that will be used (non-probing variant), otherwise the probed_addrs +are probed. + +For example: this will probe for address 0x10: + +struct v4l2_subdev *sd = v4l2_i2c_new_subdev_cfg(v4l2_dev, adapter, + "module_foo", "chipid", 0, NULL, 0, I2C_ADDRS(0x10)); + +v4l2_i2c_new_subdev_board uses an i2c_board_info struct which is passed +to the i2c driver and replaces the irq, platform_data and addr arguments. + +If the subdev supports the s_config core ops, then that op is called with +the irq and platform_data arguments after the subdev was setup. The older +v4l2_i2c_new_(probed_)subdev functions will call s_config as well, but with +irq set to 0 and platform_data set to NULL. + +Note that in the next kernel release the functions v4l2_i2c_new_subdev, +v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr will all be +replaced by a single v4l2_i2c_new_subdev that is identical to +v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments. struct video_device ------------------- diff --git a/linux/drivers/media/dvb/frontends/stv090x.c b/linux/drivers/media/dvb/frontends/stv090x.c index 62078400f..8b152bea3 100644 --- a/linux/drivers/media/dvb/frontends/stv090x.c +++ b/linux/drivers/media/dvb/frontends/stv090x.c @@ -3405,7 +3405,7 @@ static u8 stv090x_optimize_carloop(struct stv090x_state *state, enum stv090x_mod static u8 stv090x_optimize_carloop_short(struct stv090x_state *state) { - struct stv090x_short_frame_crloop *short_crl;
