[PATCH] hdspm.c: make driver name generic to avoid user confusion

[PATCH] hdspm.c: make driver name generic to avoid user confusion

[Jörn Nettingsmeier]

[-- Attachment #1: Type: text/plain, Size: 561 bytes --]

hi adi, *!


here's a trivial patch to change the driver name of hdspm.c to avoid 
irritating users who don't have the MADI version (just happened on the 
LAU list).

iiuc, no external software should make any assumptions about this 
string, so there should be no side effects, but i have been wrong before :)

please review and apply.


best,


jörn

Are braces allowed in driver names? I guess so.

"HDSPe" is also confusing, only referring to the PCIe versions. Since we
also support the old PCI versions, I suggest to name it

   "RME Hammerfall HDSP(e) Series"

On the other hand, the 'H' in "HDSP" stands for "Hammerfall", so

   "RME HDSP(e) Series"

would be more appropriate. Luckily, we don't collide with the hdsp.c
driver name, but still, it's misleading, because there are cards that
match "RME HDSP(e) Series" (like the Multiface/Digiface) but are handled
by hdsp.c instead.

What at mess. ;) Merging hdsp.c into hdspm.c would be the clean approach
to this problem, still I don't have time for this in the near future.
Maybe in July.


Given that all current variants are misleading in one way or another, we
could also leave everything as is. What do you think?


Cheers

It's allowed but better to avoid, since this entry appears as a file
name in /sys.  We've chosen generic names for the pci name entries of
sound drivers, but these look messy.  Maybe we should choose just the
module name as pci name.


thanks,

Looking through the whole tree, the majority is to use the module name
as pci_driver.name indeed.  We should follow the convention, too.

So, Adrian, please don't take this to your patchset.
I'm going to fix all sound/pci/* up once for 3.1 kernel.

OK, now I fixed the issues in all sound/pci/* drivers in sound git tree.
Now they simply use KBUILD_MODNAME in the name field.

no. MADI is way too specific, and the only reason it's there is that 
winni started with just the MADI card...

enumerate supported cards? "RME HDSP AES32, AIO, RayDAT, MADI, MADIface"
kludgy, but less potential for user confusion.
