Subject: [PATCH 0/2] iio: proximity: sx9310/sx9360: reject unsupported hardware gain values
Date: Sat, 7 Nov 2026 16:47:02 +0530 [thread overview]
Message-ID: <20261107111710.442318-1-kapoorarnav43@gmail.com> (raw)
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.
