In preparation to enabling -Wvla, remove VLA usage and replace it with fixed a fixed length array and therefore, prevent potential stack overflow attacks.

The bits for setting up the proximity diode were not setup correctly and this was causing the proximity sensor to not function correctly. This patch sets up the correct bit mask in tsl2x7x_chip_on() based on what the data sheet expects. From page 35 of the TSL2771 data sheet: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf - Bits 0-1 is the ALS gain control - Bits 2-3 is reserved (The proximity gain control on other tsl2x7x chips) - Bits 4-5 is the proximity diode select - Bits 6-7 is the LED drive strength tsl2x7x_chip_on() had the power and diode hardcoded, so these are extracted out into the settings so that these fields can be configured in the platform data. The default prox_gain is changed from 1 (2X gain) to 0 (1X gain) since the proximity gain control on the TSL2771, TMD2771, and other chips have these fields listed as reserved, and to write 0 into those bits. Verified that the proximity sensor now works correctly on a TSL2771 hooked up to a Raspberry Pi 2. Signed-off-by:

The tsl2771 and tmd2771 devices create the in_proximity0_calibscale_available sysfs attribute. These two particular devices do not support changing the proximity gain value on the chip so this patch removes that sysfs attribute. As expected, these two devices already did not create the IIO_CHAN_INFO_CALIBSCALE channel and proximity0_calibrate sysfs attribute. Page 38 of the tsl2772 data sheet shows that the proximity gain can be adjusted with bits 2-3 on the control register: https://ams.com/eng/content/download/291503/1066377/file/TSL2772_DS000181_2-00.pdf Page 35 of the tsl2771 and tmd2771 data sheets shows that bits 2-3 on the control register are reserved and changing the proximity gain is not supported: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf https://ams.com/eng/content/download/250283/976077/file/TMD2771_DS000177_2-00.pdfSigned-off-by:

Not all errors that occurred in tsl2x7x_get_prox() were correctly reported in the return value. This patch changes the error handling so that errors are now returned properly. Note that the ret variable is from the call to tsl2x7x_read_status(), and it already has the correct error check. The -EINVAL error code is for an unexpected value in the register. This patch also corrects an unnecessary word wrap in the call to le16_to_cpup() while changes are being made to this code. Signed-off-by:

There were four places where the same chunk of code was used to write to the control register. This patch creates a common function tsl2x7x_write_control_reg() to reduce duplicate code. The function tsl2x7x_chip_off() did not correctly return an error code so this patch also corrects that issue. Signed-off-by:

The tsl2X7X_platform_data structure contains the platform_power, power_on, and power_off function pointers. These power management functions should not be in the platform data. These functions were likely used before the regulator framework was put in place. There are no users of these functions in the mainline kernel. Signed-off-by:

Usually, functions responsible for reading raw data typically relies on values from iio_chan_info_enum to correctly identify the type of data to be read. There is a set of a device driver that uses the magic number 0 instead of IIO_CHAN_INFO_RAW. This patch improves the readability by replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW in six devices driver in the IIO subsystem. Signed-off-by:

This patch removes the macro IIO_DEV_ATTR_CH_OFF. The macro IIO_DEV_ATTR_CH_OFF is not required, due to the replace of it by the direct use of IIO_DEVICE_ATTR in files staging/iio/meter/ade7759.c and staging/iio/meter/ade7753.c. Signed-off-by:

The macro IIO_DEV_ATTR_CH_OFF is a wrapper for IIO_DEVICE_ATTR, with a tiny change in the name definition. This extra macro does not improve the readability and also creates some checkpatch errors.

The function magn_3d_read_raw has a switch statement handling multiple cases per channel. The first case statement uses the magic number 0, which means IIO_CHAN_INFO_RAW. Additionally, the iio_chan_spec for magn_3d_channels is configured to be IIO_CHAN_INFO_RAW. Therefore, this patch replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW. Signed-off-by:

- Add missing pinctrl description. Support is made optional as dfsdm may use internal sources (e.g. via registers) - Fix typo in IIO STM32 DFSDM filter "MANCH_F" description. Basically, this should be "falling edge = logic 0", not "1" that applies to "MANCH_R". BTW, make the description complete by describing both rising/falling edges as described in reference manuals.
