Subject: [PATCH] PCI: aardvark: Fix memory leak in driver unbind
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
Content-Transfer-Encoding: 8bit
|
|
|
|
Free config space for emulated root bridge when unbinding driver to fix
|
|
memory leak. Do it after disabling and masking all interrupts, since
|
|
aardvark interrupt handler accesses config space of emulated root
|
|
bridge.
