Instead of manually calculating the size, allocating the memory, and
writing data to it, use devm_kasprintf(). It will do all the job in one
go.

Information from sensors like temperature, which are useful for
user-space, can be exposed via sysfs.

Earlier, the driver developers had to take care of defining the attributes,
initiating them, and perform other related jobs.

But since a long time, the HWMON framework in Linux has developed
significantly. And, utilizing it will reduce lot of maintainence work
for the developers.

All the sysfs related part is handled by the framework which also allows
user-space tools, like lm-sensors, to provide the data to the user in a
simplified manner.

In "main()", the "strncat()" is given the size equal to the destination
size. Thus, in worst case scenario, the string which needs to be
suffixed, will be truncated. Fix the warning.

Variable "basepath" is defined as "/sys/bus/zio/devices/"
and variable "attribute"'s array element are in the form of "/xyz".

Thus, when the two are concatenated, the result is:
	"/sys/bus/zio/devices//xyz".

Thus remove extra forward-slash.

"strncat" needs the size of buffer that has to be concatenated, as its
3rd argument.

In function,
	"int fau_write_attribute(enum fau_attribute attr, uint32_t val)"

"strncat" when called for the second time is being overflowed. Fix that.
The goal that this code is trying to achieve can be done in one line
with "snprintf".

In function 'fa_calib_gain_update()', the first argument ('fa') passed to
'from_timer()' is not declared anywhere, and thus the build throws
compilation error.

Fix this by declaring the variable and then defining it by the value
produced by 'from_timer()'. Then we can use the same variable for the
next steps.

Variable name 'LINUX' is very ambiguous for its purpose in the makefile.
Also, this project builds as a part of COHT project which uses another
variable name 'KERNELSRC' for the same purpose. Hence, this change makes
