[PATCH] ath11k: pci: Add more MODULE_FIRMWARE() entries

[Takashi Iwai]

As there are a few more models supported by the driver, let's add the
missing MODULE_FIRMWARE() entries for them.  The lack of them resulted
in the missing device enablement on some systems, such as the
installation image of openSUSE.

While we are at it, use the wildcard instead of listing each firmware
files individually for each.

I can rewrite without wildcards if it's preferred, too.
But IMO this makes easier to maintain.

I don't feel strongly about this.

But unless I'm mistaken the above does seem to pick up a number of files
totalling around 25Mbytes. Perhaps that isn't ideal.

MODULE_FIRMWARE() itself is nothing but a hint for the required
firmware files.  The driver supports those models, hence it should
list up the mandatory firmware files that *can* be used with it;
without the firmware, the driver itself is just useless, as you know.

The rest -- how to reduce the actual sizes -- is above the kernel
modinfo covers, and it depends on the system implementation, IMO.
It can be somehow more selective, it can compress data, or it can load
the stuff on demands.


thanks,

Takashi

Thanks, understood.
If that is the case then I have no objections.
