[PATCH] mad16 C924 detection
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.

[PATCH] mad16 MPU probing
Small cleanup in mad16.c MPU probing code. Against any 2.4 kernel.
Replacing mad loops with readable switches. Removing unnecessary array

Is there a maintainer for this stuff?
Whom to feed with this kind of cleanup patches?

[PATCH] MAD16 madness
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.
