media: st-delta: avoid excessive stack usage

2025-10-15T10:03:47Z

[ Upstream commit 5954ad7d1af92cb6244c5f31216e43af55febbb7 ] Building with a reduced stack warning limit shows that delta_mjpeg_decode() copies a giant structure to the stack each time but only uses three of its members: drivers/media/platform/st/sti/delta/delta-mjpeg-dec.c: In function 'delta_mjpeg_decode': drivers/media/platform/st/sti/delta/delta-mjpeg-dec.c:427:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=] Open-code the passing of the structure members that are actually used here.

media: stm32-csi: Fix dereference before NULL check

2025-10-06T09:20:06Z

commit 80eaf32672871bd2623ce6ba13ffc1f018756580 upstream. In 'stm32_csi_start', 'csidev->s_subdev' is dereferenced directly while assigning a value to the 'src_pad'. However the same value is being checked against NULL at a later point of time indicating that there are chances that the value can be NULL. Move the dereference after the NULL check.

media: c8sectpfe: Use for_each_child_of_node_scoped()

2025-06-17T08:51:34Z

Avoids the need for manual cleanup of_node_put() in early exits from the loop. Signed-off-by: Jinjie Ruan Signed-off-by: Hans Verkuil

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37Z

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

media: platform: use (t,l)/wxh format for rectangle

2025-04-30T06:16:07Z

Standardize reporting of rectangles to (t,l)/wxh. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: use devm_kmemdup_array()

2025-04-25T13:14:34Z

Convert to use devm_kmemdup_array() and while at it, make the size robust against type changes. Signed-off-by: Raag Jadav Signed-off-by: Hans Verkuil

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

2025-04-05T08:30:12Z

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

media: platform: stm32: Add check for clk_enable()

2025-03-06T16:28:29Z

Add check for the return value of clk_enable() to gurantee the success. Fixes: 002e8f0d5927 ("media: stm32-dma2d: STM32 DMA2D driver") Cc: stable@vger.kernel.org Signed-off-by: Jiasheng Jiang Signed-off-by: Hans Verkuil

media: c8sectpfe: Call of_node_put(i2c_bus) only once in c8sectpfe_probe()

2025-03-06T16:28:28Z

An of_node_put(i2c_bus) call was immediately used after a pointer check for an of_find_i2c_adapter_by_node() call in this function implementation. Thus call such a function only once instead directly before the check. This issue was transformed by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Hans Verkuil

media: v4l: Convert the users of v4l2_get_link_freq to call it on a pad

2025-02-15T14:22:58Z

Call v4l2_get_link_freq() on a pad, instead of a control handler. This way we can soon convert v4l2_get_link_freq() to be callable only on a pad and remove the compatibility code.
