media: dvb-frontends: avoid stack overflow warnings with clang

2024-03-26T22:17:14Z

[ Upstream commit 7a4cf27d1f0538f779bf31b8c99eda394e277119 ] A previous patch worked around a KASAN issue in stv0367, now a similar problem showed up with clang: drivers/media/dvb-frontends/stv0367.c:1222:12: error: stack frame size (3624) exceeds limit (2048) in 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than] 1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe) Rework the stv0367_writereg() function to be simpler and mark both register access functions as noinline_for_stack so the temporary i2c_msg structures do not get duplicated on the stack when KASAN_STACK is enabled.

2023-12-13T10:04:46Z

If an error occurs after a successful i2c_mux_add_adapter(), then i2c_mux_del_adapters() should be called to free some resources, as already done in the remove function.

media: dvb-frontends: rtl2832: Stop direct calls to queue num_buffers field

2023-11-23T11:10:32Z

Use vb2_get_num_buffers() to avoid using queue num_buffers field directly. This allows us to change how the number of buffers is computed in the future.

media: dvb: symbol fixup for dvb_attach()

2023-09-09T07:15:11Z

In commit 9011e49d54dc ("modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted to GPL-only marked symbols. This interacts oddly with the DVB logic which only uses dvb_attach() to load the dvb driver which then uses symbol_get(). Fix this up by properly marking all of the dvb_attach attach symbols as EXPORT_SYMBOL_GPL().

Pull media updates from Mauro Carvalho Chehab: - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913 - new Intel IVSC MEI drivers - some Mediatek platform drivers were moved to a common location - Intel atomisp2 driver is now working with the main ov2680 driver. Due to that, the atomisp2 ov2680 staging one was removed - the bttv driver was finally converted to videobuf2 framework. This was the last one upstream using videobuf version 1 core. We'll likely remove the old videobuf framework on 6.7 - lots of improvements at atomisp driver: it now works with normal I2C sensors. Several compile-mode dependecies to select between ISP2400 and ISP2401 are now solved in runtime - a new ipu-bridge logic was added to work with IVSC MEI drivers - venus driver gained better support for new VPU versions - the v4l core async framework has gained lots of improvements and cleanups - lots of other cleanups, improvements and driver fixes * tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (358 commits) media: ivsc: Add ACPI dependency media: bttv: convert to vb2 media: bttv: use audio defaults for winfast2000 media: bttv: refactor bttv_set_dma() media: bttv: move vbi_skip/vbi_count out of buffer media: bttv: remove crop info from bttv_buffer media: bttv: remove tvnorm field from bttv_buffer media: bttv: remove format field from bttv_buffer media: bttv: move do_crop flag out of bttv_fh media: bttv: copy vbi_fmt from bttv_fh media: bttv: copy vid fmt/width/height from fh media: bttv: radio use v4l2_fh instead of bttv_fh media: bttv: replace BUG with WARN_ON media: bttv: use video_drvdata to get bttv media: i2c: rdacm21: Fix uninitialized value media: coda: Remove duplicated include media: vivid: fix the racy dev->radio_tx_rds_owner media: i2c: ccs: Check rules is non-NULL media: i2c: ds90ub960: Fix PLL config for 1200 MHz CSI rate media: i2c: ds90ub953: Fix use of uninitialized variables ...

media: Explicitly include correct DT includes

2023-07-19T10:57:51Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
