iio: temperature: tmp006: fix information leak in triggered buffer

2024-12-08T16:51:35+00:00

The 'scan' local struct is used to push data to user space from a triggered buffer, but it has a hole between the two 16-bit data channels and the timestamp. This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44+00:00

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.

iio: fix write_event_config signature

2024-11-03T20:33:44+00:00

write_event_config callback use an int for state, but it is actually a boolean. iio_ev_state_store is actually using kstrtobool to check user input, then gives the converted boolean value to write_event_config. Fix signature and update all iio drivers to use the new signature. This patch has been partially written using coccinelle with the following script: $ cat iio-bool.cocci // Options: --all-includes virtual patch @c1@ identifier iioinfo; identifier wecfunc; @@ static const struct iio_info iioinfo = { ..., .write_event_config = ( wecfunc | &wecfunc ), ..., }; @@ identifier c1.wecfunc; identifier indio_dev, chan, type, dir, state; @@ int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir, -int +bool state) { ... } make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio Unfortunately, this script didn't match all files: * all write_event_config callbacks using iio_device_claim_direct_scoped were not detected and not patched. * all files that do not assign and declare the write_event_config callback in the same file. iio.h was also manually updated. The patch was build tested using allmodconfig config. cc: Julia Lawall Signed-off-by: Julien Stephan Link: https://patch.msgid.link/20241031-iio-fix-write-event-config-signature-v2-7-2bcacbb517a2@baylibre.com Signed-off-by: Jonathan Cameron

iio: Switch back to struct platform_driver::remove()

2024-10-10T18:31:50+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

iio: temperature: tmp006: add triggered buffer support

2024-09-30T08:21:02+00:00

Add support for continuous data capture using triggered buffers for the tmp006 sensor. The device features a "data ready" interrupt line which is pulled down once a new measurement is ready to be read.

iio: hid-sensor: Use aligned data type for timestamp

2024-09-30T08:20:59+00:00

Use aligned_s64 for the timestamp field. Note, the actual data is signed, hence with this we also amend that. While at it, drop redundant __alignment directive.

Use dev_err_probe() (and variants) in the probe() path.
