[PATCH 5.10 358/509] platform/x86: wmi: remove unnecessary argument

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Barnabás Pőcze <pobrn@xxxxxxxxxxxxxx>

[ Upstream commit 84eacf7e6413d5e2d2f4f9dddf9216c18a3631cf ]

The GUID block is available for `wmi_create_device()`
through `wblock->gblock`. Use that consistently in
the function instead of using a mix of `gblock` and
`wblock->gblock`.
