[PATCH] b43: Simple 'fix' for radio switch LED regression

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since addition of the rfkill callback, the LED associated with the off/on
switch on the radio has not worked because essential data in the rfkill
structure is missing. When that problem was fixed, difficulties in circular
locking surfaced. This patch fixes part of the regression in that the LED
is turned on if the radio switch is on at startup. Adding the code to toggle
the LED with the switch will be more involved and would likely miss the 2.6.24
window.

John and Michael,

I was able to get the full functionality working, but with two significant
problems: (1) the LED toggled only with a switch off-on sequence, not with
each switch change and (2) the module would no longer unload cleanly due to
circular locking. I will be essentually off-line after today, and I hope that
this hack, which will make the LED appear to work correctly, can be pushed
into 2.6.24 as it is a fix, but has minimal code impact. Nearly all of the
changes are needed just to make the LED on routine available to startup.
Furthermore, I'm certain these changes will be needed when the complete fix
is available.

Larry
