Subject: [PATCH v1 1/3] ACPI: thermal: Use white space more consistently
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
The usage of white space in the ACPI thermal driver is not very
consistent, so improve that a bit.
While at it, add missing braces to if()/else in a few places.
No functional impact.
