[PATCH 1/2] drivers: ide: Include appropriate header file in ide-cd_verbose.c

[Rashika Kheria]

Include appropriate header file ide-cd.h in ide-cd_verbose.c because
function ide_cd_log_error() has its prototype declaration in ide-cd.h.
Also, include linux/ide.h because it contains certain declarations
necessary for including ide-cd.h.

This eliminates the following warnings in ide-cd_verbose.c:
drivers/ide/ide-cd_verbose.c:251:6: warning: no previous prototype for ‘ide_cd_log_error’ [-Wmissing-prototypes]

drivers/ide/ is open only to fixes for serious, real bugs - nothing
else. I wouldn't waste my time with it if I were you.

A quick check of "git log drivers/ide/" turns up a pile of fixes and
cleanups; for instance:

c2f7d1e ide: pmac: remove unnecessary pci_set_drvdata()
a6fd6063 ide: cs5536: use module_pci_driver()
58e48be ide: pmac: Remove casting the return value which is a void pointer
64110c1 ide: sgiioc4: Staticize ioc4_ide_attach_one()
70ddce8 ide: palm_bk3710: add missing __iomem annotation

The two proposed patches here are extremely low risk, don't actually
change the compiled code in any way like some of those did, and fix real
compiler warnings.

Considering the fact that IDE is about to be deleted (unless something
embedded still wants it which I hardly doubt but hey, I'm always open to
surprises), putting *any* work into that is a complete waste of time,
IMO. But it is your time so I certainly won't tell you how to spend it.

    You're right in your doubting: there are quite a lot of drivers used by 
embedded platforms that nobody has bothered to convert to libata thus far.

Hold on, what does that mean? IDE is back from the dead and used only
for embedded stuff?

Or we force people to convert drivers to libata by *deleting* ide?

No, it means that there are legacy PATA chipsets (some used by embedded
platforms) that are only supported by IDE host drivers.

If there is a need I should be able to help in converting these leftover
drivers before we delete IDE.  Once I find some time I will go over all
IDE host drivers, make a list of affected hardware and start a discussion
on IDE removal.

I know what it means - I was asking a provocative question. :)

While this is a generous offer, I'd leave it to the people who actually
need that functionality to do the conversion themselves. But this is
just me.

    Like jazz, IDE "is not dead, it just smells funny".

> Or we force people to convert drivers to libata by *deleting* ide?

    I hope not. To me, it would be a shame e.g. to delete more or less 
well-designed IDE taskfile interface to the ad-hockery that libata has in its 
place...

    You should fix "ide-cd.h" if it depends on <linux/ide.h>, not the .c file 
including it.
