Subject: [patch 07/13] ACPI/processor: Fix error handling in __acpi_processor_start()
Date: Wed, 12 Apr 2017 22:07:33 +0200 [thread overview]
Message-ID: <20170412201042.695499645@linutronix.de> (raw)
In-Reply-To: 20170412200726.941336635@linutronix.de
[-- Attachment #1: ACPI-processor--Fix-error-handling-in-__acpi_processor_start--.patch --]
[-- Type: text/plain, Size: 781 bytes --]
When acpi_install_notify_handler() fails the cooling device stays
registered and the sysfs files created via acpi_pss_perf_init() are
leaked and the function returns success.
Undo acpi_pss_perf_init() and return a proper error code.
