Subject: [resend, PATCH v1 2/2] parport: Drop even more unneeded NULL or 0 assignments
Date: Wed, 18 Oct 2023 17:59:48 +0300	[thread overview]
Message-ID: <20231018145948.1367648-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231018145948.1367648-1-andriy.shevchenko@linux.intel.com>

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.
