| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Coverity checker noted that we've already dereferenced "dev" when we check whether it's NULL. Since it's impossible that "dev" is NULL at this place this patch removes the NULL check. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | phy_read() returns a negative number if there's an error, but the error-checking code in the Vitesse driver's config_intr function triggers if phy_read() returns non-zero.

| * | ps3: fix rare issue that reenabling rx DMA failsMasakazu Mokuno2007-07-242-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown in dmesg. This meant restarting rx DMA had been rejected by the hypervisor. This issue would caused if the guest os requested starting DMA when the hypervisor thought the DMA was in progress. The state machine for DMA status of the hypervisor would be updated by processing interrupt in the hypervisor. Thus we should wait for the interrupt delivery before restarting DMA.

Unfortunately the launcher currently maps virtual device memory where shared libraries want to go. The solution is to pre-scan the args to figure out how much memory we have, then allocate devices above that, rather than down from the top possible address. This also turns out to be simpler.
