Fix Realtek RTL8192ce LED in Ubuntu (Patch attached)

[Carl Richell]

Realtek RTL8192ce driver in natty's kernel does not correctly initialize the wireless LED (i.e. the LED doesn't work). The attached patch fixes the LED.

The original patch by Larry Finger was written for 2.6.39 and does not compile against natty's kernel: http://marc.info/?l=linux-wireless&m=130247823800466&w=2

A minor change to the patch fixes the compile error and enables the wireless LED. The change is discussed here: http://marc.info/?l=linux-wireless&m=130324790201204&w=2

Please consider using the patch. This wireless card can not be used in production systems without the LED working.

[Stefan Bader (smb)]

As the variable existed in 2.6.38 (just with a slightly different name), I would propose this version.

[Stefan Bader (smb)]

Patch is in v3.0-rc1, so it should get into Oneiric by the time of rebase.

[Stefan Bader (smb)]

SRU Justification:

Impact: The driver code for the RTL8192ce wireless driver does not initialize the LED which does not allow to quickly check whether wireless is enabled.

Fix: Upstream commit from v3.0-rc1. The matter is not seen as critical upstream, so there will not be stable update.

Testcase: Patch verified by reporter to enable LED.

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag
'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be
dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

-10 kernel in proposed fixes the bug. tag updated. Thanks!
