[PATCH] mad16 C924 detection

2001-03-05 Thread Pavel Rabel


Patch is replacing 7 levels of nested ifs with something
readable. Against 2.4 kernels. I have posted this one already once,
trying again.

The driver doesn't support C924 in both PnP and non-PnP modes as it
claims. It looks like part of the code got lost or was not finished. This
patch makes it more clear what's going on. There are many places in the
driver with two different paths for C924, only one is ever used.

2000-12-10 Thread Pavel Rabel

Both MODULE_PARM and __init are removed by precompiler when not compiler
as module, so no need for ifdefs.

It is related to VGA card (at least on my system).
Enabling 'Assign IRQ for VGA' in BIOS causes the message to disapear.

[PATCH] MAD16 madness

2000-11-16 Thread Pavel Rabel

Hi,

When I saw the mad16.c driver, I just couldn't resist.
There were 7 (seven) levels of nested ifs.
It looks like more cleaning can be done, but this patch is just
reorganising the code without any functionality change and makes the 
questionable logic more readable. 

Patch against latest 2.4test, similar patch can be
written for 2.2, it's just using older API.

I am not quite sure how it will work when you try to use both ne.c and
ne2k-pci drivers in the same box. Which driver will be used for PCI card?
Maybe people with both cards are forced to use inferior driver for PCI
card.
