virtio-pci: make reset operation safer

2011-11-24T02:34:48Z

virtio pci device reset actually just does an I/O write, which in PCI is really posted, that is it can complete on CPU before the device has received it. Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.

regulator: TPS65910: Fix VDD1/2 voltage selector count

2011-11-23T14:03:52Z

Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed Signed-off-by: Mark Brown
