Check for attribute_group structures that are only stored in the attrs filed of iio_info structure. As the attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant. Done using coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct attribute_group i@p = {...}; @ok1@ identifier r1.i; position p; struct iio_info x; @@ x.attrs=&i@p; @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct attribute_group i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct attribute_group i; File size before: drivers/staging/iio/adc/ad7280a.o text data bss dec hex filename 6487 584 776 7847 1ea7 drivers/staging/iio/adc/ad7280a.o File size after: drivers/staging/iio/adc/ad7280a.o text data bss dec hex filename 6551 544 776 7871 1ebf drivers/staging/iio/adc/ad7280a.o Signed-off-by:Bhumika Goyal <bhumirks@gmail.com> Acked-by:

Changed the processing of IIO_CHAN_INFO_INT_TIME in isl29018_write_raw() to unlock the mutex and return at the end of the function if invalid input is passed in. This makes the error handling code consistent with the processing of IIO_CHAN_INFO_CALIBSCALE and IIO_CHAN_INFO_SCALE within the same function. Signed-off-by:

Add support for the AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1, AD7767-2 Analog to Digital converters. It's a family of single channel 24-bit SAR ADCs. They are all digital interface compatible and the main difference is the internal decimation rate and analog performance. For communication with the host processor a SPI interface is used. In addition the part has a data ready pin that is pulsed for one MCLK cycle when a conversion has completed and can be used as a IIO trigger.

Some triggers can only be attached to the IIO device that corresponds to the same physical device. Currently each driver that requires this implements its own trigger validation function. Introduce a new helper function called iio_trigger_validate_own_device() that can be used to do this check. Having a common implementation avoids code duplication and unnecessary boiler-plate code.

The -Wempty-body gcc warning triggers in the newly added zpa2326 driver: drivers/iio/pressure/zpa2326.c: In function 'zpa2326_dequeue_pressure': drivers/iio/pressure/zpa2326.c:578:3: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] The use of an empty statement behind 'if (...)' is harmless here, but it shows that the dev_dbg() macro is not used correctly: when the "DEBUG" macro is not set, dev_dbg() already defaults to a no-operation, though one that lets the compiler know that the arguments are used, and lets it check the format string. Fixing this also simplifies the driver. Fixes: 03b262f2 ("iio:pressure: initial zpa2326 barometer support") Signed-off-by:

The newly added __sca3000_get_base_freq function handles all valid modes of the SCA3000_REG_ADDR_MODE register, but gcc notices that any other value (i.e. 0x00) causes the base_freq variable to not get initialized: drivers/staging/iio/accel/sca3000_core.c: In function 'sca3000_write_raw': drivers/staging/iio/accel/sca3000_core.c:527:23: error: 'base_freq' may be used uninitialized in this function [-Werror=maybe-uninitialized] This adds explicit error handling for unexpected register values, to ensure this cannot happen.

This patch adds the strings 'rx', 'tx' and 'isoc' to the list of accepted identifiers when setting up a channel configuration.
