[PATCH v1 10/15] ACPI: button: Drop redundant variable from acpi_button_probe()

[Rafael J. Wysocki]

From: "Rafael J. Wysocki" <rafael.j.wysocki@xxxxxxxxx>

Local char pointer called "name" in acpi_button_probe() is redundant
because its value can be assigned directly to input->name and the
latter can be used in the only other place where "name" is read, so
get rid of it.

No intentional functional impact.
