Subject: [PATCH net-next 5/6] devlink: Clear whole devlink_flash_notify struct

From: Leon Romanovsky <leonro@...dia.com>

The { 0 } doesn't clear all fields in the struct, but tells to the
compiler to set all fields to zero and doesn't touch any sub-fields
if they exists.

The {} is an empty initialiser that instructs to fully initialize whole
struct including sub-fields, which is error-prone for future
devlink_flash_notify extensions.

Fixes: 6700acc5f1fe ("devlink: collect flash notify params into a struct")
