CVE-2025-38142

findecsensorindex() may return a negative value (e.g. -ENOENT), but its result was used without checking, which could lead to undefined behavior when passed to getsensor_info().

Add a proper check to return -EINVAL if sensor_index is negative.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

[groeck: Return error code returned from findecsensor_index]
