CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Smatch complains that snprintf() returns the number of characters, not counting the NUL terminator, which *would* have been printed if there were enough space. In other words the return value could be more than sizeof(buf). In this case, we are printing something like "ff.ff\n" which is at most 6 characters and a NUL so that's not an issue. I changed snprintf() to scnprintf() to silence the warning. But since the buffer doesn't include space for the NUL terminator, we need to make it bigger or the "\n" will be truncated off.

It's slightly cleaner to use kstrtouint() because we pass unsigned ints to adis16136_set_freq(). On 64 bit systems, if the user passed LONG_MIN then it we would get past the test against zero but crash in adis16136_set_freq() because we truncate the high bits away.

The ad7796 and ad7797 are similar to the ad7792 and ad7793 but only have a single differential input instead of two. Also some other features are missing like the programmable gain amplifier and also not all sampling frequencies supported by the ad7792/ad7793 are supported by the ad7796/ad7797. This patch adds new feature flags for the features not present in the ad7796/ad7797. The patch also adds a struct iio_info field to the chip_info struct, this becomes necessary since the ad7796/ad7797 needs a special set of sysfs attributes.

The ad7798 and ad7799 are similar to the ad7792 and ad7793 but are missing some features like the temperature sensor, being able to use an external clocksource and a few other things. This patch adds a new 'flags' fields to the chip_info struct which allows to specify which features a certain chip variant supports. The setup code will then ignore any platform data fields which are related to non supported features.

Some of the newer generation devices from the ADIS16XXX series have more registers than what can be supported with the current register addressing scheme. These devices implement register paging to support a larger register range. Each page is 128 registers large and the currently active page can be selected via register 0x00 in each page. This patch implements transparent paging inside the common adis library. The register read/write interface stays the same and when a register is accessed the library automatically switches to the correct page if it is not already selected. The page number is encoded in the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

The function __iio_add_event_config_attrs is only called once, by the function iio_device_register_eventset. If the call fails, iio_device_register_eventset calls __iio_remove_event_config_attrs. There is thus no need for __iio_add_event_config_attrs to also call __iio_remove_event_config_attrs on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f,free,a; parameter list[n] ps; type T; expression e; @@ f(ps,T a,...) { ... when any when != a = e if(...) { ... free(a); ... return ...; } ... when any } @@ identifier r.f,r.free; expression x,a; expression list[r.n] xs; @@ * x = f(xs,a,...); if (...) { ... free(a); ... return ...; } // </smpl> Signed-off-by: NJulia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: NJonathan Cameron <jic23@kernel.org>

When parsing a fixed point number IIO stops parsing the string once it has reached the last requested decimal place. This means that the remainder of the string is silently accepted regardless, of whether it is part of a valid number or not. This patch modifies the code to scan the whole string and only accept valid numbers. Since fract_mult is 0 after the last decimal place any digit that may follows won't affect the result.

For ADCs or DACs the denominator for fractional types often is a power of two. In this case we can use a shift operation instead of the rather expensive 64 bit division. This patch adds a new fractional type which expects the denominator to be specified as the log2 of the actual denominator. E.g. for ADCs and DACs this will usually be the number of significant bits.
