* V4L/DVB sh_mobile_ceu: don't check platform_get_irq's return value against zeroUwe Kleine-König2010-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | | platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use (int)irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

| | | | | | | | | | | | (S_CROP) The initial soc-camera scaling and cropping implementation turned out to be incompliant with the V4L2 API, e.g., it expected the user to specify cropping in output window pixels, instead of input window pixels.

| | | | | | | | | | | | | | | Not all video capture devices can configure arbitrary cropping, whereas the CEU module on SuperH CPUs can crop with pixel precision. However, we want to use camera cropping if possible to save bandwidth and increase the frame-rate. This patch verifies whether the camera managed to crop exactly the requested rectangle, and if not, uses host-side cropping. To be able to crop on CEU we have to preserve camera rectangle too, for which the host_priv member in struct soc_camera_device is used. We now allocate memory dynamically, thus we have to use the .put_formats() method from struct soc_camera_host_ops to free it.

There are situations, when a camera host driver provides the required format, but requires a different format from the sensor. Further, the list of formats, supported by sensors is pretty static and can be pretty good described with a constant list of structures. Whereas decisions, made by camera host drivers to support requested formats can be quite complex, therefore it is better to let the host driver do the work.

* V4L/DVB (9521): V4L: struct device - replace bus_id with dev_name(), ↵Kay Sievers2008-12-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_set_name() This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.
