[PATCH] ASoC: wm2000: Improve a size determination in wm2000_i2c_probe()

From: Markus Elfring
Date: Fri Nov 24 2017 - 02:18:14 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.
