The Linux stack is short; we need to be able to count the number of bytes used at stack on each function. So, we don't like to use variable-length arrays, as complained by smatch: drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used. The max usecase of the driver seems to be 5 bytes + 1 for the register. So, let's be safe and allocate 6 bytes for the write buffer. This should be enough to cover all cases. If not, let's print an error message. Signed-off-by:Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Using 8 URBs results in a consecutive buffer allocation of too much memory for some arm devices. As we use isochronuous transfers the number of URBs can be reduced without risking data-loss. Signed-off-by:

Commit 275ddb40 removed the lirc "protocol" but kept backwards compatibility by always listing the protocol as present and enabled. This patch further improves the logic by only listing the protocol if the lirc module is loaded (or if lirc is builtin). Signed-off-by:

Use eth_zero_addr to assign the zero address to the given address array instead of memset when second argument is address of zero. Note that the 6 in the third argument of memset appears to represent an ethernet address size (ETH_ALEN). The Coccinelle semantic patch that makes this change is as follows: // <smpl> @eth_zero_addr@ expression e; @@ -memset(e,0x00,6); +eth_zero_addr(e); // </smpl> Signed-off-by:

On built-in kernels this warning will always splat as this is part of the module init. Fix that by shifting the PAT requirement check out under the code that does the "quasi-probe" for the device. This device driver relies on an existing driver to find its own devices, it looks for that device driver and its own found devices, then uses driver_for_each_device() to try to see if it can probe each of those devices as a frambuffer device with ivtvfb_init_card(). We tuck the PAT requiremenet check then on the ivtvfb_init_card() call making the check at least require an ivtv device present before complaining.

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_register_driver(), so we can drop the manual assignment. Signed-off-by:

I noticed certain cards are currently under MEDIA_ANALOG_TV_SUPPORT but it seems they are frame grabbers (with CVBS, Svideo etc. inputs) rather than TV receivers (with analog TV tuners). MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems to drive a real camera in a laptop) but it at least doesn't select the TUNERs. Perhaps the following patch would make sense.

Gotos makes a little harder to check the code. In this particular case, the goto is doing nothing but jumping into a return. Instead, just replace the goto by the return, making it simpler. Signed-off-by: -

Current code assigns 0 to variable 'err', which makes mantis_dma_init() to return success even if mantis_alloc_buffers() fails. Fix it by checking the return value from mantis_alloc_buffers() and propagating it in the case of error. Reported-by:

To compile videobuf2-core as a module, the vb2_* tracepoints must be exported from the videodev module. Instead of exporting vb2 tracepoint symbols from v4l2-ioctl.c, move the tracepoint generation into a separate file. This patch fixes the following build error in the modpost stage, introduced by 2091f518 ("[media] videobuf2: add trace events"): ERROR: "__tracepoint_vb2_buf_done" undefined! ERROR: "__tracepoint_vb2_dqbuf" undefined! ERROR: "__tracepoint_vb2_qbuf" undefined! ERROR: "__tracepoint_vb2_buf_queue" undefined! Suggested-by:

Using adv7611_read_cable_det() for ADV7612 means that full support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available due to the need for multiple port reads to determine cable detection, and an agreed mechanism for communicating the separate statuses. This patch replaces adv7611_read_cable_det() with a functionally identical copy, commented appropriately. Earlier submissions [leading to commit 8331d30b] also set .cp_csc, which is used in a cp_read() call within adv76xx_log_status(). Signed-off-by:

Prior to commit f862f57d ("[media] media: i2c: ADV7604: Migrate to regmap"), the local variable 'val' contained the combined register reads used in the chipset version ID test. Restore this expectation so that the comparison works as it used to. Signed-off-by:
