To: John W Linville; +Cc: torvalds, kay.sievers, linux-wireless
This patch addresses two recent mail threads. The first, which was on LKML
(http://lkml.indiana.edu/hypermail/linux/kernel/1112.3/00965.html) was for a
WARNING that occurs after a suspend/resume cycle for rtl8192cu.
The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.
This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

V2 - Implement asynchronous firmware loading without any completion queue.
As suggested by Johannes Berg, the ieee80211_register_hw() call is
initiated only after the firmware is available.
John,
Although this patch fixes definite bugs, I think it should go through the
normal process for V3.4 as this process will give more time for testing. I
have tested; however, my system is unable to suspend/resume correctly, thus
this has not been tested. I have tested hibernation.
Larry
