Subject: [PATCH 0/4] HID: hid-uclogic-params: Fix NULL pointer dereferences

Hi everyone,

This series fixes 4 possible NULL pointer dereference errors
present in hid-uclogic-params.c found by Coverity.

Even though the fixes are small and very similar I made them
in 4 patches to include the Coverity ID on each of them and
make Coverity happy.

I didn't find any code calling the functions with invalid
params, but since the check is there, it's better to make sure
that it's doing its job.

Thanks,
José Expósito
