Subject: [PULL V2 18/44] e1000e: Remove extra pointer indirection
Date: Fri, 10 Mar 2023 17:35:00 +0800 [thread overview]
Message-ID: <20230310093526.30828-19-jasowang@redhat.com> (raw)
In-Reply-To: <20230310093526.30828-1-jasowang@redhat.com>
From: Akihiko Odaki <akihiko.odaki@daynix.com>
e1000e_write_packet_to_guest() passes the reference of variable ba as a
pointer to an array, and that pointer indirection is just unnecessary;
all functions which uses the passed reference performs no pointer
operation on the pointer and they simply dereference the passed
pointer. Remove the extra pointer indirection.
