[PATCH v4 08/11] PCI: aardvark: Fix memory leak in driver unbind

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pali Rohár <pali@xxxxxxxxxx>

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.
