eedc3554fe generic: b53: fix reverted error check in probe
b53_switch_detect returns value returned by b53_read8, which is 0 for
success. So fail (and return error) only if b53_switch_detect returned
something else than 0. This fixes supported and advertising being zeros
for MDIO access.

4be8c22e74 generic: ar8216: add detach callback
The current code uses the 'remove' callback to disable
packet mangle on the underlying ethernet device.
However the attached_dev is always NULL when the
'remove' callback is called by phylib, and this causes
NULL pointer dereference, like this:

The ar8216_mib_{capture,flush} functions are similar.
Move the common code into a helper and use that from
the original functions.

10d30f2d2d swconfig: make it compatible with 3.7
swconfig does not compile with 3.7 because

struct netlink_notify->pid    has been renamed to
struct netlink_notify->portid

and

struct genl_info->snd_pid     has been renamed to
struct genl_info->snd_portid

Use the new names and add compatibility patches
to 3.3 and 3.6.
