Subject: [PATCH 1/3] arm/xen: Improve a size determination in __set_phys_to_machine_multi()
Date: Sun, 4 Jun 2017 23:05:35 +0200 [thread overview]
Message-ID: <7f2ec975-9a2b-132d-77f0-559fd7eadc30@users.sourceforge.net> (raw)
In-Reply-To: <9b9230f4-0f00-e019-75b4-571e29b52998@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 4 Jun 2017 20:50:55 +0200
Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
