When subdev registration fails the subdev v4l2_dev field is left to a non-NULL value. Later calls to v4l2_device_unregister_subdev() will consider the subdev as registered and will module_put() the subdev module without any matching module_get(). Fix this by setting the subdev v4l2_dev field to NULL in v4l2_device_register_subdev() when the function fails. Signed-off-by:

EEPROMs are currently read in blocks of 16 bytes, but the em2800 is limited to 4 bytes per read. All other chip variants support reading of max. 64 bytes at once (according to the em258x datasheet; also verified with em2710, em2882, and em28174). Since em2800_i2c_recv_bytes() has been fixed to return with -EOPNOTSUPP when more than 4 bytes are requested, EEPROM reading with this chip is broken. It was actually broken before that change, too, it just didn't throw an error because the i2c adapter silently returned trash data (for all reads >1 byte !). Signed-off-by:

I2C_FUNC_SMBUS_EMUL includes flag I2C_FUNC_SMBUS_WRITE_BLOCK_DATA which signals that up to 31 data bytes can be written to the ic2 client. But the EM2800 supports only i2c messages with max. 4 data bytes. I2C_FUNC_IC2 should be set if a master_xfer function pointer is provided in struct i2c_algorithm. Signed-off-by:

Function em2800_i2c_recv_bytes() has 2 severe bugs: 1) It does not wait for the i2c read to complete before reading the received message content from the bridge registers. 2) Reading more than 1 byte doesn't work The former can result in data corruption, the latter always does. The rewritten code also superseds the content of function em2800_i2c_check_for_device(). Tested with device "Terratec Cinergy 200 USB". [mchehab@redhat.com: Fix CodingStyle issues] Signed-off-by:

The em2800 can transfer up to 4 bytes per i2c message. All other em25xx/em27xx/28xx chips can transfer at least 64 bytes per message. I2C adapters should never split messages transferred via the I2C subsystem into multiple message transfers, because the result will almost always NOT be the same as when the whole data is transferred to the I2C client in a single message. If the message size exceeds the capabilities of the I2C adapter, -EOPNOTSUPP should be returned. Signed-off-by:

[media] em28xx: IR RC: move assignment of get_key functions from *_change_protocol() functions to em28xx_ir_init() The get_key functions are independent from the selected protocol, so assign them once only at device initialization. [mchehab@redhat.com: fix a merge conflict] Signed-off-by:

The main purpose of this patch is to move the call of em28xx_release_resources() after the call of em28xx_close_extension(). This is necessary, because some resources might be needed/used by the extensions fini() functions when they get closed. Also mark the device as disconnected earlier in this function and unify the em28xx_uninit_usb_xfer() calls for analog and digital mode. Signed-off-by:

DEV_INITIALIZED of enum em28xx_dev_state state is used nowhere and there is no need for DEV_MISCONFIGURED, so remove this enum and use a boolean field 'disconnected' in the device struct instead. Signed-off-by:

This patch converts the em28xx driver over to videobuf2. It is likely that em28xx_fh can go away entirely, but that will come in a separate patch. [mchehab@redhat.com: fix a non-trivial merge conflict with some VBI patches; CodingStyle fixes] Signed-off-by:

The sliced VBI support in the tvp5150 is completely broken. And there is no support for the saa7115 sliced VBI implementation in the em28xx driver. So we remove the sliced VBI support completely. It should be possible to get it to work with the tvp5150, but that will require someone to really dig into that driver. Signed-off-by:

The ir-i2c-kbd already adds I2C IR before the name. The way it is, the devices are named as: "i2c IR (i2c IR (EM2840 Hauppaug" With is ugly and incorrect. After this patch, it is now properly displayed as: "i2c IR (WinTV USB2)" Signed-off-by: -

The em28xx-input is used by 3 different types of input devices: - devices with buttons (like cameras and grabber devices); - devices with I2C remotes; - em2860 or latter chips with RC support embedded. When the device has an I2C remote, all it needs to do is to call the proper I2C driver (ir-i2c-kbd), passing the proper data to it, and just leave the code. Also, button devices have its own init code that doesn't depend on having an IR or not (as a general rule, they don't have). So, move its init code to fix bugs introduced by earlier patches that prevent them to work. Signed-off-by:
