media: pci: Use PCI_DEVICE macros and drop zeros from pci_device_id arrays

2026-07-15T15:12:54+00:00

Some pci_device_id arrays already used the PCI_DEVICE macros, others used named initializers or list initializers. Unify all to use the PCI_DEVICE macros and (if applicable) a named initializer for .driver_data. Also drop all zeros that the compiler can care for and unify indention and spacing.

media: rc: fix race between unregister and urb/irq callbacks

2026-03-17T13:43:56+00:00

Some rc device drivers have a race condition between rc_unregister_device() and irq or urb callbacks. This is because rc_unregister_device() does two things, it marks the device as unregistered so no new commands can be issued and then it calls rc_free_device(). This means the driver has no chance to cancel any pending urb callbacks or interrupts after the device has been marked as unregistered. Those callbacks may access struct rc_dev or its members (e.g. struct ir_raw_event_ctrl), which have been freed by rc_free_device(). This change removes the implicit call to rc_free_device() from rc_unregister_device(). This means that device drivers can call rc_unregister_device() in their remove or disconnect function, then cancel all the urbs and interrupts before explicitly calling rc_free_device(). Note this is an alternative fix for an issue found by Haotian Zhang, see the Closes: tags.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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: Convert from tasklet to BH workqueue

2024-06-21T06:57:09+00:00

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
