Subject: [PATCH 22/26] can: c_can: use proper type for 'instance'

From: Wolfram Sang <wsa@...g-engineering.com>

Commit 6439fbce1075 (can: c_can: fix error checking of priv->instance in
probe()) found the warning but applied a suboptimal solution. Since, both
pdev->id and of_alias_get_id() return integers, it makes sense to convert the
variable to an integer and avoid the cast.
