Subject: wifi: mwifiex: Allocate dev name earlier for interface workqueue name
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7bab5bdb81e33cd0bc0aa848931ff47940ad54b0;p=thirdparty%2Fkernel%2Flinux.git

wifi: mwifiex: Allocate dev name earlier for interface workqueue name

The interface specific workqueues are allocated with the interface name
as part of the workqueue name. However when they are allocated, the
interface name has not been allocated, thus the "name" is actually the
pattern for the name "mlan%d". This ends up pretty ugly and could
conflict if multiple interfaces were added.

Allocate the device name earlier and use that to allocate the
workqueues. Also tweak the workqueue name patterns to add a separator
between the prefix and the interface name parts for readability.
