[PATCH net-next v2 0/7] drivers/net/phy C=1 W=1 fixes

[Andrew Lunn]

This fixes most of the Sparse and W=1 warnings in drivers/net/phy. The
Cavium code is still not fully clean, but it might actually be the
strange code is confusing Sparse.

[PATCH net-next v2 1/7] net: phy: at803x: Avoid comparison is always false warning

[Andrew Lunn]

By placing the GENMASK value into an unsigned int and then passing it
to PREF_FIELD, the type is reduces down from ULL. Given the reduced
size of the type, the range checks in PREP_FAIL() are always true, and
-Wtype-limits then gives a warning.

By skipping the intermediate variable, the warning can be avoided.

[PATCH net-next v2 6/7] net: phy: cavium: Improve __iomem mess

[Andrew Lunn]

The MIPS low level register access functions seem to be missing
__iomem annotation. This causes lots of sparse warnings, when code
casts off the __iomem. Make the Cavium MDIO drivers cleaner by pushing
the casts lower down into the helpers, allow the drivers to work as
normal, with __iomem.

bus->register_base is now an void *, rather than a u64. So forming the
mii_bus->id string cannot use %llx any more. Use %px, so this kernel
address is still exposed to user space, as it was before.

[PATCH net-next v2 7/7] net: phy: mdio-octeon: Cleanup module loading dependencies

[Andrew Lunn]

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.

Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.

Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

s/octoen/octeon/
Add MODULE_SOFTDEP()
