Subject: wireless: Print wiphy name in sysfs.
X-Git-Tag: firefly_0821_release~7613^2~3670^2~78^2^2~36
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cfd8e12f42746df396ecbdf7a1d8e92e8e4dbb97;p=firefly-linux-kernel-4.4.55.git

wireless: Print wiphy name in sysfs.

The index cannot be used to reliably reconstruct a phy
name, so explicitly add the phy name to sysfs so that scripts
can figure out the parent phy device for a particular
wireless interface.
