media: Revert "media: dvb-usb: Fix unexpected infinite loop in dvb_usb_read_remote_control()"

2024-08-08T19:40:34Z

This reverts commit 2052138b7da52ad5ccaf74f736d00f39a1c9198c. This breaks the TeVii s480 dual DVB-S2 S660. The device has a bulk in endpoint but no corresponding out endpoint, so the device does not pass the "has both receive and send bulk endpoint" test. Seemingly this device does not use dvb_usb_generic_rw() so I have tried removing the generic_bulk_ctrl_endpoint entry, but this resulted in different problems. As we have no explanation yet, revert. $ dmesg | grep -i -e dvb -e dw21 -e usb\ 4 [ 0.999122] usb 1-1: new high-speed USB device number 2 using ehci-pci [ 1.023123] usb 4-1: new high-speed USB device number 2 using ehci-pci [ 1.130247] usb 1-1: New USB device found, idVendor=9022, idProduct=d482, +bcdDevice= 0.01 [ 1.130257] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 1.152323] usb 4-1: New USB device found, idVendor=9022, idProduct=d481, +bcdDevice= 0.01 [ 1.152329] usb 4-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 6.701033] dvb-usb: found a 'TeVii S480.2 USB' in cold state, will try to +load a firmware [ 6.701178] dvb-usb: downloading firmware from file 'dvb-usb-s660.fw' [ 6.701179] dw2102: start downloading DW210X firmware [ 6.703715] dvb-usb: found a 'Microsoft Xbox One Digital TV Tuner' in cold +state, will try to load a firmware [ 6.703974] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw' [ 6.756432] usb 1-1: USB disconnect, device number 2 [ 6.862119] dvb-usb: found a 'TeVii S480.2 USB' in warm state.

media: uvcvideo: Fix custom control mapping probing

2024-07-22T12:22:20Z

Custom control mapping introduced a bug, where the filter function was applied to every single control. Fix it so it is only applied to the matching controls. The following dmesg errors during probe are now fixed: usb 1-5: Found UVC 1.00 device Integrated_Webcam_HD (0c45:670c) usb 1-5: Failed to query (GET_CUR) UVC control 2 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 3 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 6 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 7 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 8 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 9 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 10 on unit 2: -75 (exp. 1).

media: em28xx: Add support for MyGica UTV3

2024-06-29T10:20:05Z

The MyGica UTV3 Analog USB2.0 TV Box is a USB video capture card that has analog TV, composite video, and FM radio inputs, an IR remote, and provides audio only as Line Out, but not over USB. Mine is prepared for an FM tuner, but not equipped with one. Support for FM radio is therefore missing. The device contains: - Empia EM2860 USB bridge - Philips SAA7113 video decoder - NXP TDA9801T demodulator - Tena TNF931D-DFDR1 tuner - ST HCF4052 demux, switches input audio to Line Out Signed-off-by: Nils Rothaug Signed-off-by: Sean Young Signed-off-by: Hans Verkuil

media: b2c2: flexcop-usb: fix flexcop_usb_memory_req

2024-06-24T09:05:07Z

smatch generated this warning: drivers/media/usb/b2c2/flexcop-usb.c:199 flexcop_usb_memory_req() warn: iterator 'i' not incremented and indeed the function is not using i or updating buf. The reason this always worked is that this function is called to write just 6 bytes (a MAC address) to the USB device, and so in practice there is only a single chunk written. If we ever would need to write more than one chunk, this function would fail since each chunk would read from or write to the same buf address. Rewrite the function to properly handle this.

media: Convert from tasklet to BH workqueue

2024-06-21T06:57:09Z

The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. This patch converts drivers/media/* from tasklet to BH workqueue. Based on the work done by Tejun Heo Signed-off-by: Allen Pais Signed-off-by: Hans Verkuil
