Subject: ACPI: processor: perflib: Rearrange unregistration routine
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5be583c695ed4d94211cc28282a42092b137f988;p=linux.git

ACPI: processor: perflib: Rearrange unregistration routine

Rearrange acpi_processor_unregister_performance() to follow a more
common error handling pattern and drop a redundant "return" statement
from the end of it.

No expected functional impact.
