media: videobuf2: use sgtable-based scatterlist wrappers

2025-06-27T10:13:01+00:00

commit a704a3c503ae1cfd9de8a2e2d16a0c9430e98162 upstream. Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*() functions have to be called with the number of elements originally passed to dma_map_sg_*() function, not the one returned in sgt->nents.

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

2025-03-06T16:28:29+00:00

The smsdvb_module_init() returns without checking the retval from smscore_register_hotplug(). If the smscore_register_hotplug() failed, the module failed to install, leaving the smsdvb_debugfs not unregistered.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

media: videobuf2-core: copy vb planes unconditionally

2024-11-07T11:55:46+00:00

Copy the relevant data from userspace to the vb->planes unconditionally as it's possible some of the fields may have changed after the buffer has been validated. Keep the dma_buf_put(planes[plane].dbuf) calls in the first `if (!reacquired)` case, in order to be close to the plane validation code where the buffers were got in the first place.
