i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by <linux/i2c.h> work with const i2c_device_id. So mark the non-const structs as const.

Ultrasonic sensor srf10 is quite similar to srf08 and now also supported by the driver as device tree compatible string. It was necessary to prepare the source for supplementary sensors. This is done by enum srf08_sensor_type. The most significiant difference between srf08 and srf10 is another range and values of register gain (in the driver it's call sensitivity). Therefore the array of it is extended and dependent of the sensor type. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

platform_get_irq() returns an error code, but the ad7606_par driver ignores it and always returns -ENODEV. This is not correct and, prevents -EPROBE_DEFER from being propagated properly.

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a SPI device registered via OF will always match a legacy SPI device ID and that the MODALIAS reported will always be of the form spi:<device>. There is an ACPI method to enumerate such devices via specific ACPI ID and use of compatible strings. It will not work for the drivers which have no OF match ID table present. Besides this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

STM32 ADC allows each channel to be sampled with a different sampling time, by setting SMPR registers. Basically, value depends on local electrical properties. Selecting correct value for sampling time highly depends on analog source impedance. There is a manual that may help in this process: 'How to get the best ADC accuracy in STM32...' This patch allows to configure minimum sampling time via device tree, either for: - all channels at once: st,min-sample-time-nsecs = <10000>; - independently for each channel (must match "st,adc-channels" list): st,adc-channels = <0 1>; st,min-sample-time-nsecs = <5000 10000>; Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

STM32 ADC allows each channel to be sampled with a different sampling time. There's an application note that deals with this: 'How to get the best ADC accuracy in STM32...' It basically depends on analog input signal electrical properties (depends on board). Add optional 'st,min-sample-time-nsecs' property so this can be tuned in dt.

Four fields in struct fpgaimage are char arrays of length MAX_STR (256). The amount of data read into these buffers is controlled by a length field in the bitstream file read from userspace. If a corrupt or malicious firmware file was supplied, kernel data beyond these buffers can be overwritten arbitrarily. This patch adds a check of the bitstream's length value to ensure it fits within the bounds of the allocated buffers. An error condition is returned from gs_read_bitstream if any of the reads fail.
