Hi,
the whitespace and coding-style fixes in r1397 changed a few places which should have been left untouched or changed differently for various reasons: - Mixing uninitialized and initialized local variables leads to confusion. - ft2232_spi error cases should have gotten some error handling, and that's the reason the curly braces were there. - Depending on whom you ask about the C99 standard, a comma after the last element of an array initializer will cause another empty array element to be allocated, and that increases array size by 1 and may break some code which assumes certain fields to be nonzero. - Sometimes the introduced linebreaks look worse than before. - Fixing typos/wording in some places would have been nice given that those places were touched anyway. - If we insist on spelling "ASUS" all uppercase because the vendor said so, we have to spell "LPC Bridge" with an uppercase B because the datasheet said so. - #if/#else/#endif are sometimes hard to follow, and a comment at the #endif can improve readability a lot.
Comments welcome.

Indeed. Unfortunately I didn't find any beautiful solution which fit in 80 columns. The second line should be moved a bit to the right, but then we violate the 80 column limit even more. Ideas anyone?
some comments apply of course to all other instances of the discussed problem too.

yes, violate the §$&§$ 80 column limit (scnr :) the function could be renamed... and board_pciid_enable is also a very long name for a struct that's used a lot.

looks fine imo. board_match_pci_card_ids could also be renamed to board_match_pci_ids and if you are at it please change the comment of it: /* * Match boards on PCI IDs and subsystem IDs. * Second set of IDs can be main only or missing completely. */ const static struct board_pciid_enable *board_match_pci_card_ids(enum board_match_phase phase)

aaaand if we change board_match_pci_card_ids we should also change pci_card_find to pci_dev_find or something like that... :)
and now i better stop looking for such stuff.

Well, if we rename that one, we'd have to call it pci_dev_subsys_find, and that's a net loss from the 80 column perspective, but it may indeed clarify the code. Further input is appreciated.

oh my. now that i see the code, i think renaming the board enables to board_match is really a bad idea. mainly because we use "match" as verb in other places, but here as substantive. e.g. static const struct board_match *board_match_cbname a function that matches boards according to their cbname should return a board, not a "board match". it is just a question of taste, but i find it awful :)
the wiki table is named board_info hmhm maybe board_detail, but that's long.. :/ what about just "board"? another way to mitigate "my" problem would be to no use match as a verb for the method names, but using "get" or "find" instead.

It's a trap! The struct is there to match a board, so struct board_match is exactly the right name for the _type_. The name of the function is another thing, you could probably call it match_board_match_cbname, but that would be silly, so we can either call it match_board_cbname or board_match_cbname. And the name of the variable which stores the result of the function call is even another thing, and there the name board might be appropriate.

"get" has the wrong semantic implication for the cbname matching, and "find" as in board_find_cbname suffers from the same problem because we're NOT interested in finding the cbname of the board, but rather in looking for a board which matches the supplied cbname.

pci_dev_find() looks for a device matching the supplied vendor+dev IDs. pci_card_find() looks for a device matching the supplied vendor+dev+subvendor+subdev IDs.
The name "card" was picked to allow differentiating between PCI devices (cards) which share vendor+dev ID, but have different subvendor+subdev IDs. That's pretty common for network cards where dozens of vendors use the same network chip (and thus fixed vendor+dev ID), but completely different PCBs.

New stripped down version.
Turns out that trailing commas in initializers are allowed by C99: http://c0x.coding-guidelines.com/6.7.8.html
Fixup of r1397: - Mixing uninitialized and initialized local variables leads to confusion. - ft2232_spi error cases should have gotten some error handling, and that's the reason the curly braces were there. - Fixing typos/wording in some places would have been nice given that those places were touched anyway.

Fixup of r1397:
- Mixing uninitialized and initialized local variables leads to confusion.
- ft2232_spi error cases should have gotten some error handling, and
that's the reason the curly braces were there.
- Fixing typos/wording in some places would have been nice given that
those places were touched anyway.
