2009-01-14pvrusb2: Fix misleading comment caused by earlier commitMauro Carvalho Chehab
From: Mike Isely <isely@pobox.com> Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw internal API regarding i2c chip debug register access. However that change failed to also update the corresponding function comment describing the API. As driver maintained I never saw a request for an ack on that change; there probably should have been one especially since the manner in which this API operates was changed - its interface is now entangled with a v4l specific struct and I would have preferred to keep this API clear of moving-target v4l-isms such as this one if at all possible which is why I had done it the way I did before. But whatever. This commit at least fixes the comment issue. Priority: normal Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

From: Mike Isely <isely@pobox.com> Implement a new internal function to create a string device identifier.

The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe. kernel-sync: Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-01-13[PATCH] Terratec Cinergy DT XS Diversity new USB ID (0ccd:0081)Patrick Boettcher
From: Nicolas Fournier <nicolasfournier@yahoo.com> The following patch adds support for a new version of the Terratec Cinergy DT USB XS Diversity Dual DVB-T TV tuner stick. The USB ID of the new stick is 0ccd:0081. The hardware of the stick has changed, when compared to the first version of this stick, but it still uses quite standard components, so that only minor changes are needed to the sources. The patch has been successfully tested with hotplugging the device and then 2 x tzap and 2 x mplayer, to watch two different TV programs simultaneously. The stick works with both, the old and new firmwares: - dvb-usb-dib0700-1.10.fw and - dvb-usb-dib0700-1.20.fw Priority: normal Signed-off-by: Nicolas Fournier <nicolasfournier@yahoo.com> Signed-off-by: Patrick Boettcher <pb@linuxtv.org>

2009-01-12zoran: Get rid of extra module ref countTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The zoran driver does a module_get/put of THIS_MODULE on device open/close. This isn't necessary as the kernel does this automatically. Clean up the failure path of zoran_open() somewhat. Make the dprintk()s on open/close a higher debug level and make the user count printed take the current open/close into account.

2009-01-12zoran: Remove zr36057_adr fieldTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The driver should only use the kernel mapped io address, zr36057_mem, and not the PCI bus address, zr36057_adr. Since the latter is only printed out once, there is no need to save it in the driver data structure. There was some old code that looked like it was for the Alpha architecture which would use the PCI bus address. It probably no longer applies to modern kernels.

2009-01-12zoran: Use pci device table to get card typeTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Instead of using custom code, just let the device layer look it up for us from the pci device table. This requires extending the pci device table to list each known card, plus a catch-all entry for the cards that don't have sub-system vendor/device data. Improve some of the info and error messages too. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Jean Delvare <khali@linux-fr.org>
2009-01-12zoran: Remove global device arrayTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The driver was keeping a global array with an entry for each zoran device probed. It was a leftover from when the driver didn't dynamically allocate the driver data for each device. There was only one use left, in the video device's ->open() method, looking up the struct zoran for the opened device from the minor number. This can be done better with video_get_drvdata(). Since zoran_num is now only used in the pci driver's ->probe() method, it doesn't need to be an atomic_t and be static. There is a race if multiple zoran cards could be probed at the same time, but currently the probe method for a given driver is single threaded.

This way all of the entries will be correctly set to -1 if someone changes BUZ_MAX to a value other than 4. Adjust some of the parameter help text too.

2009-01-11vivi: Implements 4 inputs on viviMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> This patch adds the capability of selecting between 4 different inputs on vivi driver. Input 0 is the normal color bar, while inputs 1-3 are modified color bars. This allows testing input selection on userspace applications and serves as an implementation model for other drivers. The current approach allows a maximum of 10 different inputs, since the input name generator assumes that we need just one digit to present the input. It shouldn't be hard to modify it to present a bigger name of inputs, but, in fact, it doesn't make much sense of doing it for this test driver.

Since pre-emption is enabled then it is safe to de-allocate the memory if you first unlink each URB. In this instance you are safe since pre-emption is disabled. If pre-emption and irqs are not disabled then call usb_kill_urb(), else call usb_unlink_urb(). Thanks to Douglas for tracking down this bug originally!!!
