[PATCH net-next 0/2] net: phy and dsa random fixes/cleanups

From: Florian Fainelli <f.fainelli@gmail.com>

Hi David,

These two patches were already present as part of my attempt to make
DSA modules work properly, these are the only two "valid" patches at
this point which should not need any further rework.

Thanks!

  net: phy: fixed: allow setting no update_link callback
  net: dsa: bcm_sf2: factor interrupt disabling in a function

[PATCH net-next 1/2] net: phy: fixed: allow setting no update_link callback

From: Florian Fainelli <f.fainelli@gmail.com>
Date: 2015-01-21 00:42:21 

fixed_phy_set_link_update() contains an early check against a NULL
callback pointer, which basically prevents us from removing any
previous callback we may have set. The users of the fp->link_update
callback deal with a NULL callback just fine, so we really want to allow
"removing" a link_update callback to avoid dangling callback pointers
during e.g: module removal.

[PATCH net-next 2/2] net: dsa: bcm_sf2: factor interrupt disabling in a function

From: Florian Fainelli <f.fainelli@gmail.com>
Date: 2015-01-21 00:42:22 

Factor the interrupt disabling in a function: bcm_sf2_intr_disable()
since we are doing the same thing in the setup and suspend paths.

Series applied, thanks.
