Subject: [PATCH v3] brcmfmac: expose firmware config files through modinfo

From: Matthias Brugger <[email protected]>

Apart from a firmware binary the chip needs a config file used by the
FW. Add the config files to modinfo so that they can be read by
userspace.

Signed-off-by: Matthias Brugger <[email protected]>

---

Changes in v3:
Use only two more generic wildcards.

Changes in v2:
In comparison to first version [0] we use wildcards to enumerate the
firmware configuration files. Wildcard support was added to dracut
recently [1].
