[PATCH] Staging: iio/accel: Improvements to data types when using kstrto*

[Andreas Ruprecht]

As was pointed out by Dan, some data types could be changed from long (as we only had strict_strtol here before) to a smaller type by using the corresponding kstrto* functions.

I'm not sure about the sca_3000_set_free_fall_mode() function, as to what could be in buf. From my interpretation it's only a matter of a 0/1 decision, but I wanted to have someone else give their opinion on that before changing it.
The same probably applies to sca_3000_set_ring_int() in the file sca3000_ring.

Regards,
Andreas Ruprecht
