Compile error in drivers/ide/osb4.c in 240-t10p6

Compile error in drivers/ide/osb4.c in 240-t10p6

[Rasmus Andersen]

<ugh> Forgot to cc linux-kernel

Hi.

I get the following error when trying to compile 2.4.0-test10pre6
without procfs support:

drivers/ide/osb4.c: In function `pci_init_osb4':
drivers/ide/osb4.c:264: `osb4_revision' undeclared (first use in this function)
drivers/ide/osb4.c:264: (Each undeclared identifier is reported only once
drivers/ide/osb4.c:264: for each function it appears in.)
make: *** [drivers/ide/osb4.o] Error 1

The variable, osb4_revision, is inside a #ifdef CONFIG_PROC_FS block but
I was not able to discern if the line where it is referred should be
#ifdef'ed also. The following patch moves the variable declaration out-
side the #ifdef block, as a blind guess...

This patch, and a lot of others of a similar nature, are in my test10pre6
compile patch at

Hi Arjan.

Thanks for the pointer. However my test build still barfs in the final
link phase because we (in t10p6) morphed drivers/pcmcia/cs.c::pcmcia_
request_irq into (the static) cs_request_irq. The rename part
broke the two other places in cs.c where pcmcia_request_irq was
referenced and the static part made its usage in drivers/net/pcmcia/
ray_cs.c a bit awkward.

Since I won't presume to question the decision to rename the function
the following patch propagates the rename to the rest of the kernel.
Furthermore, I presumed to remove the static part so that the ray_cs
driver was free to use it. I have added David Hinds and Corey Thomas
(the raylink driver maintainer) to the cc on this mail so they can
decide what the proper solution is.

Meanwhile, this patch makes my test kernel build:

This is what went to Linus, and David Hinds ack'd it.

It should be un-morphed back to the way it was.  It was an error that
slipped into a patch I was preparing, because I was hand-editing the
"diff" output to accommodate some changes between the kernel tree and
the separate PCMCIA package.

[coreythomas]

ray_cs was imported to the kernel as one of the first test drivers by
Linus.  At the time, he wanted to get rid of the CardServices(function...)
interface and replace it with pcmcia_function calls.  It seems that
the correct fix would be to change pcmcia_request_irq to RequestIRQ
like all the other drivers use.  Or, change all the other drivers.  In
any case I know of no reason for ray_cs to be unique.
