Subject: [PATCH v1 1/3] ACPI: scan: Change acpi_scan_init() return value type to void
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
The only caller of acpi_scan_init(), acpi_init(), doesn't check its
return value, so turn it into a void function.
This avoids complaints from the Smatch static checker that the
function should return a negative error code when it fails, which
is not really a problem in this particular case.
No intentional functional impact.
