Subject: [PATCH 2/2] ASoC: tas5805m: Improve a size determination in
 tas5805m_i2c_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 16 Sep 2024 10:20:12 +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.
