Subject: drm/i915/guc: Rename client->cookie to match use
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=357248bfe592f8a34be5fb76bb8154710403785e;p=linux-beck.git

drm/i915/guc: Rename client->cookie to match use

The client->cookie is a shadow of the doorbell->cookie value, so rename
it to indicate its association with the doorbell, like the doorbell id
and offset.
