[Bug 38673] prism54 driver requires new firmware name

[TedKisner]

Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-20-686 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
In kernel version 2.6.15-20, the prism54 driver attempts to load a non
existant firmware file:

<snip>
Loaded prism54 driver, version 1.2
islusb: Request firmware for 'isl3886' failed: -2
eth2: could not upload firmware ('isl3886')
eth2: islpci_reset: failure
islusb: unable to boot device
<snip>

The firmware file exists in /lib/firmware/2.6.15-20-*, but it has the
old name "isl3890".

The card I am using is an older "fullmac" prism54, rather than one of
the new "softmac" varieties.  From reading the prism54.org website, it
sounds like the latest kernel driver is now unified and supports both
types of prism54 chipsets.  I'm assuming this is why the required
firmware name has changed to "isl3886", which is the name of the newer
softmac chips.

Renaming the file (isl3890 --> isl3886) solves this problem.  The
firmware is then successfully uploaded to the card.

cheers,
