2011-10-24m68k/mac: Fix mac_irq_pending() for PSC MACE and SCCFinn Thain1-1/+1
Add missing return statement. The docs say that the level 4 PSC IRQs relate to MACE DMA and SCC. Since those drivers don't call mac_irq_pending() this patch has no affect. But it should be fixed all the same, since it can be useful for MACE debugging. Signed-off-by: Finn Thain <[email protected]> Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-10-24m68k/mac: Fix compiler warning in via_read_time()Finn Thain1-17/+23
The algorithm described in the comment compares two reads from the RTC but the code actually reads once and compares the result to an uninitialized value. This causes the compiler to warn, "last_result maybe used uninitialized". Make the code match the comment, fix the warning and perhaps improve reliability. Tested on a Quadra 700.

2011-10-24hwmon: (pmbus) Always call _pmbus_read_byte in core driverGuenter Roeck6-15/+17
Always call _pmbus_read_byte() instead of pmbus_read_byte() in PMBus core driver. With this change, device specific read functions can be implemented for all registers. Since the device specific read_byte function is now always called, we need to be more careful with page validations. Only fail if the passed page number is larger than 0, since -1 means "current page". Signed-off-by: Guenter Roeck <[email protected]> Reviewed-by: Robert Coulson <[email protected]>

2011-10-24hwmon/f71882fg: Make the decision wether to register fan attr. per fanHans de Goede1-65/+54
Before this patch the f71882fg driver completely fails to initialize on systems which have reserved settings in the pwm enable register, and it disables all auto pwm sysfs attributes if any fan is controlled by a digital sensor reading. This patch changes the fail to initialize into don't register any attributes for the fan for which there are reserved settings in the pwm enable register and also makes the not registering of auto pwm sysfs attributes a per fan thing.

2011-10-24hwmon: (pmbus) Don't return errors from driver remove functionsGuenter Roeck10-21/+18
Driver remove functions have an error return value, but rarely return an error in practice. If a driver does return an error from its remove function, the driver won't be unloaded and is expected to stay alive. pmbus_do_remove() is defined as returning an int, but always returns 0 (no error). Calling code passes that return value on to high level driver remove functions, but does not evaluate it and removes driver data even if pmbus_do_remove() returned an error (which it in practice never does). Even if this code could never cause a real problem, it is nevertheless conceptually wrong. To reduce confusion and simplify the code, change pmbus_do_remove() to be a void function, and have PMBus client drivers always return zero in their driver remove functions.

2011-10-24ipv4: tcp: fix TOS value in ACK messages sent from TIME_WAITEric Dumazet5-9/+15
There is a long standing bug in linux tcp stack, about ACK messages sent on behalf of TIME_WAIT sockets. In the IP header of the ACK message, we choose to reflect TOS field of incoming message, and this might break some setups. Example of things that were broken : - Routing using TOS as a selector - Firewalls - Trafic classification / shaping We now remember in timewait structure the inet tos field and use it in ACK generation, and route lookup. Notes : - We still reflect incoming TOS in RST messages. - We could extend MuraliRaja Muniraju patch to report TOS value in netlink messages for TIME_WAIT sockets. - A patch is needed for IPv6 Signed-off-by: Eric Dumazet <[email protected]> Signed-off-by: David S.

2011-10-24rtnetlink: Add missing manual netlink notification in dev_change_net_namespacesEric W. Biederman1-0/+1
Renato Westphal noticed that since commit a2835763e130c343ace5320c20d33c281e7097b7 "rtnetlink: handle rtnl_link netlink notifications manually" was merged we no longer send a netlink message when a networking device is moved from one network namespace to another. Fix this by adding the missing manual notification in dev_change_net_namespaces. Since all network devices that are processed by dev_change_net_namspaces are in the initialized state the complicated tests that guard the manual rtmsg_ifinfo calls in rollback_registered and register_netdevice are unnecessary and we can just perform a plain notification.
