This series is a continuation of [1] with a focus on logging improvements (in
the style of commit b11e5f6a3a5c ("net: sunhme: output link status with a single
print.")). I have included several of Rolf's patches in the series where
appropriate (with slight modifications). After this series is applied, many more
messages from this driver will come with driver/device information.
Additionally, most messages (especially debug messages) have been condensed onto
one line (as KERN_CONT messages get split).
[1] https://lore.kernel.org/netdev/4686583.GXAFRqVoOG@eto.sf-tec.de/
Rolf Eike Beer (3):
sunhme: remove unused tx_dump_ring()
sunhme: forward the error code from pci_enable_device()
sunhme: switch to devres
Sean Anderson (10):
sunhme: Remove version
sunhme: Return an ERR_PTR from quattro_pci_find
sunhme: Regularize probe errors
sumhme: Convert FOO((...)) to FOO(...)
sunhme: Clean up debug infrastructure
sunhme: Convert printk(KERN_FOO ...) to pr_foo(...)
sunhme: Use (net)dev_foo wherever possible
sunhme: Combine continued messages
sunhme: Use vdbg for spam-y prints
sunhme: Add myself as a maintainer

Module versions are not very useful:

While we're at it, inline the author and use the driver name a bit more.

This already returns a proper error value, so pass it to the caller.

In order to differentiate between a missing bridge and an OOM condition,
return ERR_PTRs from quattro_pci_find. This also does some general linting
in the area.

This fixes several error paths to ensure they return an appropriate error
(instead of ENODEV).

This not only removes a lot of code, it also fixes the memleak of the DMA
memory when register_netdev() fails.

Remove all the single-use debug conditionals, and just collect the debug
defines at the top of the file. HMD seems like it is used for general debug
info, so just redefine it as pr_debug. Additionally, instead of using the
default loglevel, use the debug loglevel for debugging.

This is a mostly-mechanical translation of the existing printks into
pr_foos. In several places, I have pasted messages which were broken over
several lines to allow for easier grepping.

Wherever possible, use the associated netdev (or device) when printing
errors or other messages. This makes it immediately clear what device
caused the error, and provides more information than just the device name.

This driver seems to have been written under the assumption that messages
can be continued arbitrarily. I'm not when this changed (if ever), but such
ad-hoc continuations are liable to be rudely interrupted. Convert all such
instances to single prints. This loses a bit of timing information (such as
when a line was constructed piecemeal as the function executed), but it's
easy to add a few prints if necessary. This also adds newlines to the ends
of any prints without them.
Since (almost every) debug print included the name of the function, include
it automatically.

I know you are only reindenting it, but I dislike moving the variable up to
the top of the function. Since the kernel is C99 meanwhile the variable could
be declared just in the for loop. And when touching this anyway I think we
could get rid of the magic "4" by using ARRAY_SIZE(qp->happy_meals). Or just
replace the whole thing with memset(qp->happy_meals, 0, sizeof(qp-
>happy_meals)).

I have a similar patch around, but yours catches more places.

Completely independent of this driver, but I wonder if there is no generic
function to print these 10/100/* full/half duplex strings? There are several
drivers doing this as a quick grep shows.

Hm, I thought this style was discouraged.

Yeah, that avoids the whole problem.

There's some functions to print just one link mode, but I think generally the
full advertising word is printed in debugs. I'm not too worried since this is
just for debug.
One of my goals is to convert this driver to phylib, but I haven't dived very
deep into it.
