Please add
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
before any #include to prefix the pr_<level> dmesg output.
If you _really_ want __func__ with each output, you could use
#define pr_fmt(fmt) KBUILD_MODNAME ":%s: " fmt, __func__
though I think __func__ isn't particularly useful.

then this could become
pr_err("input sensor_data not initialized\n");
Also, there's no real need to terminate messages with sentence
ending ".". dmesg output generally isn't a sentence.

also consider:
pr_debug("raw temp: %#x\n", raw);

Generic OOM messages are already emitted by devm_kzalloc.
This could be written as:
priv = devm_kzalloc(etc...)
if (!priv)
return -ENOMEM;
