2009-01-28bttv: make tuner card info more consistentTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The bttv card database structure had a "tuner" field that was the input number of the tuner input or UNSET for no tuner. However, the only values it could ever be are 0 and UNSET. Having a tuner on an input other than 0 didn't work and was never used. There is also a "tuner_type" field that can be set to TUNER_ABSENT to indicate no tuner, which makes "tuner = UNSET" redundant. In many cases, tuner_type was set to UNSET when there was no tuner, which isn't quite correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet known. So, I changed cards where "tuner == UNSET" to always have tuner_type of TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it. I have the card setup code set the card's tuner_type (not the card type's tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the setup code. Various places that check if the card has a tuner will now look for this instead of checking the card type's "tuner" field. Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C client call instead of after issuing it. Overall, on ia32 this decreases compiled code size by about 24 bytes and reduces the data size by 640 bytes. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-01-28bttv: Fix TDA9880 norm setting codeTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The code to set the norm for the TDA9880 analog demod was comparing btv->norm, an index into the bttv driver's norm array, to V4L2_STD_NTSC, which is a bit flag that's part of the V4L2 API. This doesn't work of course and results in the PAL path always being taken. What's more, it modified the bttv_tvcards[] entries for cards using the TDA9880. This is wrong because changing the norm on one card will also affect other cards of the same type. Writing to bttv_tvcards is also bad because it should be read-only or even devinitdata. Changing the norm would also cause the audio to become unmuted. Have the code get called for both norm setting and audio input setting (which where the gpios are set) to avoid needed to modify bttv_tvcards.

2009-01-28bttv: norm value should be unsignedTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The norm value in the driver is an index into an array and the the driver doesn't allow it to be negative or otherwise invalid. It should be unsigned but wasn't in all places. Fix some structs and functions to have the norm be unsigned. Get rid of useless checks for "< 0". Most of the driver code can't handle a norm value that's out of range, so change some ">= BTTV_TVNORMS" checks to BUG_ON(). There's no point in silently ignoring invalid driver state just to crash because of it later.

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!!!
