Subject: [SCSI] hpsa: enable bus master bit after pci_enable_device
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5cb460a640cc733fee03adbbc9257246e6c3de08;p=linux-beck.git

[SCSI] hpsa: enable bus master bit after pci_enable_device

pci_disable_device() disables the bus master bit and pci_enable_device does
not re-enable it.  It needs to be enabled.
