2011-10-24be2net: don't create multiple RX/TX rings in multi channel modeSathya Perla
When the HW is in multi-channel mode based on the skew/IPL, there are 4 functions per port and so not enough resources to create multiple RX/TX rings for each function.

2011-10-24be2net: refactor VF setup/teardown code into be_vf_setup/clear()Sathya Perla
Currently the code for VF setup/teardown done by a PF (if_create, mac_add_config, link_status_query etc) is scattered; this patch refactors this code into be_vf_setup() and be_vf_clear(). The if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ is created; so these cmds are now modified to use the MCCQ instead of MBOX.

2011-10-24be2net: add vlan/rx-mode/flow-control config to be_setup()Sathya Perla
When a card is reset due to EEH error recovery or due to a suspend, rx-mode config (promisc/mc) is not being sent to the FW. be_setup() is called in these flows and is the best place for such config/re-config cmds. Hence include rx-mode, vlan and flow-control config in be_setup(). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.

2011-10-24m68k/mac: Fix compiler warning in via_read_time()Finn Thain
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.

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.

2011-10-24hwmon/f71882fg: Make the decision wether to register fan attr. per fanHans de Goede
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 Roeck
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.
