[PATCH] ASoC: da7218: Improve a size determination in da7218_i2c_probe()

From: Markus Elfring
Date: Thu Nov 23 2017 - 14:50:44 EST


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.

This issue was detected by using the Coccinelle software.
