626f5eaed1 hwmon: (ftsteutates) Use permission specific SENSOR[_DEVICE]_ATTR variants
Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code,
to improve readbility, and to reduce the chance of inconsistencies.

Also replace any remaining S_<PERMS> in the driver with octal values.

The conversion was done automatically with coccinelle. The semantic patches
and the scripts used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches/hwmon/.

This patch does not introduce functional changes. It was verified by
compiling the old and new files and comparing text and data sizes.

1dad2e958a hwmon: (ftsteutates) constify i2c_device_id
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.

7576750f03 hwmon: (ftsteutates) Fix clearing alarm sysfs entries
sysfs store functions should return the number of bytes written.
Returning zero results in an endless loop.

4c8702b3cd hwmon: (ftsteutates) Fix potential memory access error
Using set_bit() to set a bit in an integer is not a good idea, since
the function expects an unsigned long as argument, which can be 64 bit
wide. Coverity reports this problem as

>>>     CID 1364488:  Memory - illegal accesses  (INCOMPATIBLE_CAST)
>>>     Pointer "&ret" points to an object whose effective type is "int"
>>>	(32 bits, signed) but is dereferenced as a wider "unsigned
+long" (64 bits, unsigned).  This may lead to memory corruption.
245                     set_bit(1, (unsigned long *)&ret);

Just use BIT instead.
