[Qemu-devel] [PATCH] sii3112: Remove unneeded exit function
Posted by BALATON Zoltan 7 years, 7 months ago 
An exit function was mistakenly left here but it's not needed because
the PCI bars are organised differently in this device. Calling this
exit function during device_del was causing an abort with
memory_region_del_subregion: `Assertion subregion->container == mr' failed.

Applied to ppc-for-2.12, thanks.
