[resend, PATCH v1 2/2] parport: Drop even more unneeded NULL or 0 assignments

From: Andy Shevchenko
Date: Wed Oct 18 2023 - 11:54:22 EST


kzalloc() gives us a zeroed memory, no need to explicitly assing 0 or
NULL or similar to the members of the data structure that has been
allocated with the above mentioned API.

Note, the initializstion of full_list member is not needed anymore
as list_add_tail will rewrite the contents of the prev and next
pointers.
