drivers/net/wireless/hostap/hostap_ioctl.c:1666:6: warning: variable 'ret' set but not used
Keep in mind Im not sure if this is the right fix for this, so please
feedback is appreciated.

NACK please read the code instead of just patching blindly to cure a
compile issue. For example read this big block:
I suppose I did look blindly.. the whole ret = 0; then ret = *
got me.. then I figured maybe its just a return.
/* FIX:
* It seems to be enough to set roaming mode for a short moment to
* host-based and then setup scanrequest data and return the mode to
* firmware-based.
*
* Master mode would need to drop to Managed mode for a short while
* to make scanning work.. Or sweep through the different channels and
* use passive scan based on beacons. */
So.. it seems to me you likely want to flip back to
HFA384X_ROAMING_FIRMWARE *after* you've tried to issue the
HFA384X_RID_SCANREQUEST, even if it has failed. So the compile fix
should require just changing the last return statement of the function
to return ret value.
so this is a simple return ret;
And for 802.11 there is no need to cc netdev and lkml. Just use linux-wireless.
Luis
is netdev even used nowadays?
anyways I'll resend this. Thanks for the feedback and info..
