media: m88ds3103: Implement 3103c chip support

2026-03-25T17:27:25Z

Hauppauge 416e products have moved to using the 3103C satellite demod. This demod behaves mostly like a 3103b, but has different initialization, clocking, and lock operations. This Linux code was reverse egineered entirely using a Windows reference driver.

media: au0828: Add new Hauppauge HVR1265 and ImpactVCB-e

2026-03-17T09:50:19Z

New HVR1265 and ImpactVCB-e devices are PCIe baords with USB controller and essentially embedded Hauppauge 950Q. HVR1265 - digital+analog TV, S-Video, and audio inputs ImpactVCB-e - Composite, S-Video, and audio inputs This also fixes AU8522_COMPOSITE_CH4, which was missing from video routing.

media: si2168: fw 4.0-11 loses warm state during sleep

2026-03-17T09:50:19Z

Ignoring version 4.0-11 firmware leads to non functional devices after sleep on all Hauppauge DVB devices containing the si2168 and firmware version 4.0-11. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: si2168: Fix i2c command timeout on embedded platforms

2026-03-17T09:50:19Z

On many embedded platforms i2c responses through USB are not returned as quickly, plus constantly banging on the i2c master receive essentially deadlocks the driver. Inserting a 3ms delay between i2c receive calls and extending the timeout fixes all tested platforms. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: dib8000: avoid division by 0 in dib8000_set_dds()

2026-03-16T15:30:20Z

In dib8000_set_dds(), 1 << 26 (67108864) divided by e.g. 1 apparently can't fit into 16-bit variable unit_khz_dds_val, being truncated to 0; this will cause division by 0 while calling dprintk() with debugging enabled (via the module parameter). Use s32 instead of s16 to declare the variable, getting rid of the cast to u16 in the *else* branch as well... Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

media: mn88443x: Use %pe format specifier

2025-10-17T09:31:15Z

The %pe format specifier is designed to print error pointers. It prints a symbolic error name (eg. -EINVAL) and it makes the code simpler by omitting PTR_ERR() This patch fixes this cocci report: ./dvb-frontends/mn88443x.c:698:3-10: WARNING: Consider using %pe to print PTR_ERR() ./dvb-frontends/mn88443x.c:713:3-10: WARNING: Consider using %pe to print PTR_ERR() Signed-off-by: Ricardo Ribalda Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: dvb: Use int type to store negative error codes

2025-10-14T13:07:36Z

Change the 'ret' variable from u8/u32 to int to store zero or negative error codes returned by other functions. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but it's ugly as pants. No effect on runtime. Signed-off-by: Qianfeng Rong Signed-off-by: Hans Verkuil
