2022-02-18iio:adc:ad7091r: Move exports into IIO_AD7091R namespace.Jonathan Cameron
In order to avoid unnecessary pollution of the global symbol namespace move the core/library functions into a specific namespace and import that into the various specific device drivers that use them. For more information see https://lwn.net/Articles/760045/ An alternative here would be to conclude that we are unlikely to see support for the other ad7091r parts in the near future and just merge the two modules into one supporting just the i2c -5 variant.

2022-02-18iio:st-sensors: Remove duplicate MODULE_*Jonathan Cameron
The core module and type specific core modules are made up of several files. There is no benefit in duplicating the MODULE_* macros in each file so remove them. Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and it still worked, making it clear not all of these blocks were needed.

The mma8452_driver declares both of_match_table and i2c_driver.id_table match-tables, but its probe() function only checked for of matches. Add support for i2c_device_id matches. This fixes the driver not loading on some x86 tablets (e.g. the Nextbook Ares 8) where the i2c_client is instantiated by platform code using an i2c_device_id.

2022-01-23iio: hw_consumer: Use struct_size() helper in kzalloc()Gustavo A. R. Silva
Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows. Also, address the following sparse warnings: drivers/iio/buffer/industrialio-hw-consumer.c:63:23: warning: using sizeof on a flexible structure when using CF='-Wflexible-array-sizeof' Link: https://github.com/KSPP/linux/issues/174 Signed-off-by: Gustavo A.

2022-01-23iio: sps30: Use sysfs_emit()Lars-Peter Clausen
sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. Use sysfs_emit() to format the custom `cleaning_period` device attribute of the sps30 driver.
