2010-09-28wl1271: Change supported channel order for a more optimal scanJuuso Oikarinen
The mac80211 inserts channels into a scan request in the same order the driver registers them.

2010-09-28wl1271: Fix scan race conditionJuuso Oikarinen
In the scan state machine, the wl1271_mutex is unlocked first then relocked, and then the scan state variables are modified. This makes it possible for ieee80211_scan_complete to be called twice in some scenarios, as the scan completion event from the firmware may be processed while the mutex is unlocked. To fix the issue, move the ieee80211_scan_complete call last in the function. This is generally safer, but there still may be issues is functions calling the scan state machine rely on states checked before the unlocking of the global mutex. (forward ported from 2.6.32 -- this is not strictly needed anymore, because the mutex doesn't need to be unlocked anymore, but I'm applying this change anyway, so that the call to ieee80211_scan_complete is in the same place) Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Saravanan Dhanabal <ext-saravanan.dhanabal@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

2010-09-16net/wireless: use generic_file_llseek in debugfsArnd Bergmann
The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "John W.
