Trying to fix the MT7610U chipset driver by MediaTek so it's usable on modern Linux kernels and with nl80211/NetworkManager (and not completely breaking on old ones, maybe...)

Config file won't open using legacy filp_open (btrfs) #3

Some file systems may not support this legacy call. Replace it with vfs open call...

It could cause weird issues like all config values being 0, causing 802.11N not to work, etc...

Thanks to @mkreisl for his help with this. The fix was simple after we figured out what was going on.

    use vfs_read if no f_op->read

There's also an f_op->write in here, I'll have to figure out what the use case for this is.
