media: af9035: prevent buffer overflow on write
When less than 3 bytes are written to the device, memcpy is called with
negative array size which leads to buffer overflow and kernel panic. This
patch adds a condition and returns -EOPNOTSUPP instead.
Fixes bugzilla issue 64871
[[email protected]: fix a merge conflict and changed the
condition to match the patch's comment, e. g. len == 3 could
also be valid]
