X-Git-Tag: v4.10-rc1~71^2^2~148

[media] winbond-cir: Use kmalloc_array() in wbcir_tx()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".

This issue was detected by using the Coccinelle software.
