Subject: ste_dma40: Improve a size determination in d40_of_probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=71660223f50036e67a2a66cf55815fa665639d3a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ste_dma40: Improve a size determination in d40_of_probe()

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.
