2007-10-22V4L/DVB (6336): cx8802: Plug memory leak when unregistering a driverTrent Piepho
When a cx8802 sub-driver was unregistered, the struct cx8802_driver, which was kmalloc()ed by cx8802_register_driver(), was deleted from the list of drivers, but never freed.

list_for_each_entry Less code and more efficient. Got ride of a variable that counted the number of devices in cx8802_unregister_driver() but was never used. Looked leftover from a cut&paste.

2007-10-22V4L/DVB (6334): cx88: Change (struct cx8802_dev)->drvlist to a list_head and ↵Trent Piepho
fix bugs It was a struct cx8802_driver for no apparent reason. Nothing uses a cx8802_driver in the cx8802_dev struct. The only field that was used was devlist, a list_head. The code in cx8802_remove() that removed any loaded sub-drivers was broken. It would delete the current list entry, but didn't use list_for_each_safe. It also called list_del() on the list _head_ inside the list_for_each loop? It would crash if it was run, which I don't think can ever happen. Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded first. So there isn't any way for a sub-driver to still be loaded when cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes the PCI card while the drivers are loaded? So I left some code in to handle that if it's actually possible. It will remove the sub-drivers from the device cx8802_remove() was called on, and only that device. If one has two DVB cards and unplugs one, there is no reason to unload the DVB drivers for both cards. I have no way to test this, but it can't be worse than what was there before. cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested driver on that device. It first loops over the cx8802 device list looking for the device it was passed, which is pointless. It doesn't need to find the device pointer in the list, as it already has the pointer. The list_head in the cx8802_driver struct, which joins all the _drivers_ attached to a device, was named devlist. Changed that to drvlist, since the devlist is used for a list of _devices_ in other cx8802 structs.

2007-10-22V4L/DVB (6333): cx88: Change void* card_priv to struct vp3054_i2c_stateTrent Piepho
card_priv was only used to store a pointer to the vp3054 state struct. There's no need to use a void * since it doesn't have multiple types. Make the field conditional on VP3045 support. It was already conditional on DVB support, but it's only used if VP3045 support is on, so that makes for a better option to check.

2007-10-22V4L/DVB (6185): cx88-alsa: Add mute controls, change control namesTrent Piepho
Add two mute controls. One mutes everything, the other just mutes the analog pass-through output. Rename the existing volume control. The controls are now: Playback Volume Playback Switch Capture Switch These names might seem odd, but I believe they are more correct. The previous "Capture Volume" control didn't actually effect the volume of the captured audio. Instead it controls the volume of the analog pass-thought output. It appears that pass-through controls like this are usually considered to be in the playback direction, not capture. For example, "CAPTURE feedback Playback Volume" is the name used for a control that appears to have the same effect in the ca0106 driver. We only have one volume control, so we can omit the "CAPTURE feedback" part. If someone where to add PCM playback support to the driver, then this would be the volume control.

This patch adds retries to the hp hardware handler, and utilizes the MP_RETRY flag of dm-multipath. For now in the hp handler, if we get a pg_init completed with a check condition we just assume we can retry the pg_init command. We make this assumption because of incomplete data on specific check condition code of the HP hardware, and because testing has shown the HP path initialization command to be idempotent. The number of times we retry is settable via the "pg_init_retries" multipath map feature.

2007-10-20dm mpath: add retry pg initDave Wysochanski
This patch allows a failed path group initialisation command to be retried. It adds a generic MP_RETRY flag and a "pg_init_retries" feature to device-mapper multipath which limits the number of retries. 1. A hw handler sends a path initialization command to the storage and the command completes with an error code indicating the command should be retried. 2. The hardware handler calls dm_pg_init_complete() with MP_RETRY set in err_flags to ask the dm multipath core to retry. 3. If the retry limit has not been exceeded, pg_init() is retried. Otherwise fail_path() is called. If you are using the userspace multipath-tools or device-mapper-multipath package, you can set pg_init_retries in the 'device' section of your /etc/multipath.conf file. For example: features "2 pg_init_retries 7" The number of PG retries attempted is reported in the 'dmsetup status' output.
