52a58f9df1 net/ethernet/sis/sis190: Use module_pci_driver to register driver
Removing some boilerplate by using module_pci_driver instead of calling
register and unregister in the otherwise empty init/exit functions.

720a43efd3 drivers:net: Remove unnecessary OOM messages after netdev_alloc_skb
Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM
messages is unnecessary as there is already a dump_stack
after allocation failures.

Other trivial changes around these removals:

Convert a few comparisons of pointer to 0 to !pointer.
Change flow to remove unnecessary label.
Remove now unused variable.
Hoist assignment from if.

1dd06ae8db drivers/net: fix up function prototypes after __dev* removals
The __dev* removal patches for the network drivers ended up messing up
the function prototypes for a bunch of drivers.  This patch fixes all of
them back up to be properly aligned.

Bonus is that this almost removes 100 lines of code, always a nice
surprise.

0968a9d1c8 drivers/net/ethernet/sis/sis900.c: fix error return code
The function sis900_probe() return 0 for success and negative value
for most of its internal tests failures. There is one exception
that is error case going to err_out_cleardev:. Fore this error case,
the function abort its success execution path, but returns non negative
value, making it difficult for a caller function to notice the error.

This patch fixes the error case that do not return negative value.

This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.

A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

57d6d456cf sis900: stop using net_device.{base_addr, irq} and convert to __iomem.
- pci_resource_start() can be removed from sis900_get_mac_addr() because
  the IO range is maped and stored into the device private struct early
  in the device probe function.
- the driver contains a few direct accesses to low IO ports that forbid
  to re(#)define the usual out{l, w, b} macros.

aaba215ca0 MII: fix Kconfig dependencies for MII
MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well.  It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled.  This caused a dependency error.

Resolved the dependency by selecting NET_CORE when MII is
selected.

88f07484cc drivers/net/ethernet/*: Enabled vendor Kconfig options
Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.

This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers.  In
addition, by enabling all the new Kconfig options does not add
any un-expected options.
