2021-01-06media: gp8psk: initialize stats at power control logicMauro Carvalho Chehab
commit d0ac1a26ed5943127cb0156148735f5f52a07075 upstream. As reported on: https://lore.kernel.org/linux-media/20190627222020.45909-1-willemdebruijn.kernel@gmail.com/ if gp8psk_usb_in_op() returns an error, the status var is not initialized. Yet, this var is used later on, in order to identify: - if the device was already started; - if firmware has loaded; - if the LNBf was powered on. Using status = 0 seems to ensure that everything will be properly powered up. So, instead of the proposed solution, let's just set status = 0.

2020-12-30media: netup_unidvb: Don't leak SPI master in probe error pathLukas Wunner
commit e297ddf296de35037fa97f4302782def196d350a upstream. If the call to spi_register_master() fails on probe of the NetUP Universal DVB driver, the spi_master struct is erroneously not freed. Likewise, if spi_new_device() fails, the spi_controller struct is not unregistered. Plug the leaks. While at it, fix an ordering issue in netup_spi_release() wherein spi_unregister_master() is called after fiddling with the IRQ control register. The correct order is to call spi_unregister_master() *before* this teardown step because bus accesses may still be ongoing until that function returns.

2020-12-30media: sunxi-cir: ensure IR is handled when it is continuousSean Young
commit 3f56df4c8ffeb120ed41906d3aae71799b7e726a upstream. If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.

2020-12-30media: gspca: Fix memory leak in probeAlan Stern
commit e469d0b09a19496e1972a20974bbf55b728151eb upstream. The gspca driver leaks memory when a probe fails. gspca_dev_probe2() calls v4l2_device_register(), which takes a reference to the underlying device node (in this case, a USB interface). But the failure pathway neglects to call v4l2_device_unregister(), the routine responsible for dropping this reference. Consequently the memory for the USB interface and its device never gets released. This patch adds the missing function call.

[ Upstream commit 1ed36ecd1459b653cced8929bfb37dba94b64c5d ] To comply with the intended usage of the V4L2 selection target when used to retrieve a sensor image properties, adjust the rectangles returned by the imx219 driver. The top/left crop coordinates of the TGT_CROP rectangle were set to (0, 0) instead of (8, 8) which is the offset from the larger physical pixel array rectangle. This was also a mismatch with the default values crop rectangle value, so this is corrected. Found with v4l2-compliance. While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and CROP_BOUNDS have the same size as the non-active pixels are not readable using the selection API. Found with v4l2-compliance.

[ Upstream commit a08ad6339e0441ca12533969ed94a87e3655426e ] The are two instances of sizeof() being used incorrectly. The sizeof(void *) is incorrect because urb_buffer is a char ** pointer, fix this by using sizeof(*dev->urb_buffer). The sizeof(dma_addr_t *) is incorrect, it should be sizeof(*dev->urb_dma), which is a dma_addr_t and not a dma_addr_t *. This errors did not cause any issues because it just so happens the sizes are the same.

2020-12-02media: vb2: set cache sync hints when init buffersSergey Senozhatsky
We need to set ->need_cache_sync_on_prepare and ->need_cache_sync_on_finish when we initialize vb2 buffer. Currently these flags are set/adjusted only in V4L2's vb2_queue_or_prepare_buf(), which means that for the code paths that don't use V4L2 vb2 will always tell videobuf2 core to skip ->prepare() and ->finish() cache syncs/flushes. Fix this by setting cache sync hints for new buffers; except VB2_MEMORY_DMABUF buffers, for which DMA exporter syncs caches.

Starting with firmware version 10 the GET/SET_HDMI_VERSION message was removed and GET/SET_AUTO_POWER_ON was added. The removal of GET/SET_HDMI_VERSION caused the probe of the Pulse-Eight to fail. Add a version check to handle this gracefully. Also show (but do not set) the Auto Power On value.

2020-12-01media: pulse8-cec: fix duplicate free at disconnect or probe errorHans Verkuil
Commit 601282d65b96 ("media: pulse8-cec: use adap_free callback") used the adap_free callback to clean up on disconnect. What I forgot was that in the probe it will call cec_delete_adapter() followed by kfree(pulse8) if an error occurs. But by using the adap_free callback, cec_delete_adapter() is already freeing the pulse8 struct. This wasn't noticed since normally the probe works fine, but Pulse-Eight published a new firmware version that caused a probe error, so now it hits this bug. This affects firmware version 12, but probably any version >= 10. Commit aa9eda76129c ("media: pulse8-cec: close serio in disconnect, not adap_free") made this worse by adding the line 'pulse8->serio = NULL' right after the call to cec_unregister_adapter in the disconnect() function. Unfortunately, cec_unregister_adapter will typically call cec_delete_adapter (unless a filehandle to the cec device is still open), which frees the pulse8 struct. So now it will also crash on a simple unplug of the Pulse-Eight device. With this fix both the unplug issue and a probe() error situation are handled correctly again. It will still fail to probe() with a v12 firmware, that's something to look at separately.

Since commit 528222d853f9 ("media: rc: harmonize infrared durations to microseconds"), the calculation of the chk period is wrong. As a result, all reported IR will have incorrect timings.
