2009-07-05net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy
This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2009-06-23V4L/DVB (12131): BUGFIX: An incorrect Carrier Recovery Loop optimization ↵Manu Abraham
table was being loaded for a given chip version. This would cause the optimization in tuning not to be applied and thus a failed expectation, in tuning speed increment. The patch swaps the tables in use. It also fixes a possible one in a million condition where state->dev_ver implies an older Cut (Cut < 2.0, eventhough the driver doesn't attach to any Cut older than 2.0) or even negative (due to a bad I2C bus master driver) for the card combination.

2009-06-23V4L/DVB (11913): cx231xx: TRY_FMT should not actually set anythingTrent Piepho
In the TRY_FMT handler the function get_scale() is called to find what the scaler hardware will produce for a requested size. The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale, unsigned int *hscale) saves the calculated scale values into both the pointer arguments and into dev's hscale and vscale fields. TRY_FMT shouldn't actually change anything in the device state. The code to in get_scale() that writes to dev->[hv]scale can just be deleted. In all cases when dev's fields should be modified, get_scale() was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was getting updated anyway. This didn't actually cause a problem because nothing ever actually made use of the hscale and vscale fields. I changed cx231xx_resolution_set() to use those fields rather than re-calculate them with a call to get_scale(). Updating [hv]scale in cx231xx_resolution_set() isn't necessary because every call of cx231xx_resolution_set() was already preceded by a call to get_scale() or setting the [hv]scale fields, so they will be always be up-to-date w.r.t. width and height. Removing the call to get_scale() from cx231xx_resolution_set() allowed making get_scale() a static function, which is a good thing for something with such a short name. There is already another function with the same name in the em28xx driver, but that one is static.

2009-06-23V4L/DVB (11912): em28xx: Use v4l bounding/alignment functionTrent Piepho
The v4l function has a better algorithm for aligning image size. It appears that the em2800 can only scale by 50% or 100%, i.e. the only heights supported might be 240 and 480. In that case the old code would set any height other than 240 to 480. Request 240 get 240, but request 239 and then you get 480. Change it to round to the nearest supported value.

The v4l function has a better algorithm for aligning image size. The existing code was casting pointers to u32 and to unsigned int into pointers to u16. This could mess up if someone passed in an image size greater than 65,535 and on big-endian platforms it won't work at all. The existing bounding code would shrink an image if it was too big, but returned ERANGE if it was too small. The code will not shrink or expand as necessary.

2009-06-23V4L/DVB (11901): v4l2: Create helper function for bounding and aligning imagesTrent Piepho
Most hardware has limits on minimum and maximum image dimensions and also requirements about alignment. For example, image width must be even or a multiple of four. Some hardware has requirements that the total image size (width * height) be a multiple of some power of two. v4l_bound_align_image() will enforce min and max width and height, power of two alignment on width and height, and power of two alignment on total image size. It uses an efficient algorithm that will try to find the "closest" image size that meets the requirements.

2009-06-23V4L/DVB (12119): pvrusb2: Re-fix hardware scaling on video standard changeMike Isely
The cx25840 module's VBI initialization logic uses the current video standard as part of its internal algorithm. This therefore means that we probably need to make sure that the correct video standard has been set before initializing VBI. (Normally we would not care about VBI, but as described in an earlier changeset, VBI must be initialized correctly on the cx25840 in order for the chip's hardware scaler to operate correctly.) It's kind of messy to force the video standard to be set before initializing VBI (mainly because we can't know what the app really wants that early in the initialization process). So this patch does the next best thing: VBI is re-initialized after any point where the video standard has been set.

2009-06-23V4L/DVB (12118): pvrusb2: Fix hardware scaling when used with cx25840Mike Isely
The cx25840 module requires that its VBI initialization entry point be called in order for hardware-scaled video capture to work properly - even if we don't care about VBI. Making this behavior even more subtle is that if the capture resolution is set to 720x480 - which is the default that the pvrusb2 driver sets up - then the cx25840 bypasses the hardware scaler. Therefore this problem does not manifest itself until some other resolution, e.g. 640x480, is tried. MythTV typically defaults to 640x480 or 480x480, which means that things break whenever the driver is used with MythTV. This all has been known for a while (since at least Nov 2006), but recent changes in the pvrusb2 driver (specifically in regards to sub-device support) caused this to break again. VBI initialization must happen *after* the chip's firmware is loaded, not before. With this fix, 24xxx devices work correctly again. A related fix that is part of this changeset is that now we re-initialize VBI any time after we issue a reset to the cx25840 driver. Issuing a chip reset erases the state that the VBI setup previously did. Until the HVR-1950 came along this subtlety went unnoticed, because the pvrusb2 driver previously never issued such a reset. But with the HVR-1950 we have to do that reset in order to correctly transition from digital back to analog mode - and since the HVR-1950 always starts in digital mode (required for the DVB side to initialize correctly) then this device has never had a chance to work correctly in analog mode! Analog capture on the HVR-1950 has been broken this *ENTIRE* time. I had missed it until now because I've usually been testing at the default 720x480 resolution which does not require scaling... What fun. By re-initializing VBI after a cx25840 chip reset, correct behavior is restored. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
