[PATCH 0/2] iio: proximity: sx9310/sx9360: reject unsupported hardware gain values

[Arnav Kapoor]

sx9310_write_gain() and sx9360_write_gain() accept any integer and
squeeze ilog2() of it into the register field. Values other than the
advertised 1, 2, 4 and 8 are silently rounded, wrapped or (for 0 and
negative values) turned into the maximum code, and the write reports
success. sx9324 already rejects such values; this does the same for the
other two. One patch per driver, as the Fixes tags differ.

Compile-tested only (W=1); I don't have SX9310 or SX9360 hardware.
