Remove redundant condition check
Remove not necessary if-else block for checking DT entry because else
part will never be picked as in absence of device node, probe will
fail in initial stage only.
Remove unused id->driver_data entries
As id->driver_data is not used in driver source. So no need in
Keeping these entries in id_table

Probe was not happening in Patch v1 due to removal of .id_table.As the
intention of this patch is not to change any functionality, also
changes looks simple enough.So, didn't verified Patch v1 over hardware
You should *ALWAYS* verify patches before sending them out.
Will keep in mind
I assume you've now properly tested this one ?
Hence fixing the issues in Patch v1 and posting patch v2
Changes for v2:
- Keep the id_table entries
- Keep the id->driver_data to 0

What's the purpose of this ? It doesn't save any memory or CPU cycle.
Idea is to remove unnecessary code, variables and if possible to reduce
lines of code for example here by eliminating obvious branching.
Regarding memory or cpu cyles, no difference could be because of
compiler optimization
