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.

non-mandatory The atmel,trigger-edge-type was never imposed by the driver. Make things right and remove this property from the mandatory list. This will not break existing nodes because according to the binding they should have this property. However, the driver does not impose it and it works without it, the property selects the trigger type, and without it, the driver will have no trigger available, which is the case on some boards which do not have access to the trigger pin. This will avoid generating this warning for example: */arch/arm/boot/dts/at91-sama7g5ek.dt.yaml: adc@e1000000: 'atmel,trigger-edge-type' is a required property From schema: */Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> Acked-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20211217095401.583821-1-eugen.hristev@microchip.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2022-01-23iio: hw_consumer: Use struct_size() helper in kzalloc()Gustavo A. R. Silva1-2/+2
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.

2022-01-23adis: simplify 'adis_update_bits' macrosNuno Sá1-8/+4
There's no need to use '__builtin_choose_expr' to choose the right call to 'adis_update_bits_base()'. We can change the 'BUILD_BUG_ON()' condition so that it makes sure only the supported sizes are passed in. With that, we can just use 'sizeof(val)' as the size argument of 'adis_update_bits_base()'.
