John,
Please drop the patch with this subject. I think I can do a better job than this.

Commit message:
=============================================
A recent LKML thread
(http://lkml.indiana.edu/hypermail/linux/kernel/1112.3/00965.html)
discusses warnings that occur during a suspend/resume cycle. The driver
attempts to read the firmware file before userspace is ready, leading to the
following warning:
WARNING: at drivers/base/firmware_class.c:537 _request_firmware+0x3f6/0x420()
For rtl8192cu, the problem is fixed by storing the firmware in a global buffer
rather than one allocated per device. The usage count is increased when
suspending and decreased when resuming. This way, the firmware is retained
through a suspend/resume cycle, and does not have to be reread.
This patch should fix the bug reported in
https://bugzilla.redhat.com/show_bug.cgi?id=771002.
Note: This patch also touches rtl8192ce as the "firmware" loaded message
is now printed in the wrong place.
