this patch adds a new driver for the Silicon Labs Si470x FM Radio Receiver. It should also work for the identical ADS/Tech FM Radio Receiver (formerly Instant FM Music) as soon as I find out the USB Vendor and Product ID. The driver is inspired by several other USB and radio drivers, but mainly from the D-Link DSB-R100 USB radio (dsbr100.c). The USB stick currently has an Si4701 FM RDS radio receiver. But the other Si470x devices are pin and register compatible, so that in the future the driver can easily be patched to support these too. Therefore I named the driver radio-si470x and the configuration option usb-si470x. The driver itself just provides the control function over the radio. For getting audio back, the device support the USB audio class, which is implemented in the already existing driver. I tested the driver in the last days, until it now satisfies all my functionality and robustness requirements. The application I used for testing was kradio. Signed-off-by:

The file drivers/media/video/videodev.c defines both video_device_alloc and video_device_release. These are essentially just kzmalloc and kfree, respectively, but it seems better to use video_device_release, as done in the other media files, rather than kfree, in case the implementation some day changes. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * E = video_device_alloc(...); if (E == NULL) S ... when != video_device_release(...,(T1)E,...) when != if (E != NULL) { ... video_device_release(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != video_device_release(...,(T2)E,...) when != if (E != NULL) { ... video_device_release(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by:

Video_device_alloc returns the result of a kzalloc. In this case, the value is stored in a local variable which is not copied elsewhere before the point of the error return (video_register_device does not save its first argument anywhere if it returns a negative value). Thus, a video_device_release it needed before the error return. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * E = video_device_alloc(...); if (E == NULL) S ... when != video_device_release(...,(T1)E,...) when != if (E != NULL) { ... video_device_release(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != video_device_release(...,(T2)E,...) when != if (E != NULL) { ... video_device_release(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by:

Changeset 7e65d6e8f6df removed a very bad hack on mmap(). However, the fixes weren't considering usermap and overlay memory models. This were breaking direct reading from /dev/video?, used mostly by mpeg aware drivers. Thanks to Steven Toth <stoth@linuxtv.org> for reporting the issue and bissecting it. Signed-off-by: -

This driver supports cameras with USB ID 174f:a311 or 05e1:0501, and the ov965x sensors. These devices are found in some Asus laptops and probably somewhere else. It is based on the stk11xx driver written by Nicolas Vivien Signed-off-by:

saa7134: remove the Avermedia Super 007 from eeprom detection The card made it into the Philips' Tigers eeprom detection and falls through. Since it has attracted already others to follow, which are wrongly identified as TIGER_S then, move it to the usual analog initialization. Signed-off-by:

V4L/DVB (7013): bw-qcam: add module parameter 'force_init' to skip polite auto-detection prior to direct initialization Setting force_init=1 bypasses the friendly auto-detection by polling the status register, and instead attempts to initialize the qcam directly. Not friendly to other parallel devices, but much more reliable than the auto-detection. Signed-off-by:

In order to videobuf_iolock to work, mmap_mapper should be called first. Otherwise, an OOPS is generated. On some cases, .mmap file handler used to took some time to be called. On those situations, mmap_mmapper() were called after iolock. This patch properly waits for mmap_mapper to be called, otherwise generating an error. Signed-off-by: -

IR were not working for Winfast XP 2000 TV. Gabor Nyekhelyi <n0gabor@vipmail.hu> wrote a hack some time ago: http://marc.info/?l=linux-video&m=116362609323281&w=2 This patch fixes CodingStyle and commits the hack. I suspect that the proper solution would be to find the proper mask_keydown for this IR. Anyway, better to have this patch as a workaround.
