2010-01-04wl1271: fix timeout in wl1271_top_reg_readJuha Leppanen
I noticed a timeout bug in /drivers/net/wireless/wl12xx/wl1271_spi.c In the current code you cannot tell why you exited the "poll for data ready" do-while loop if exiting was done after the last possible loop. Then timeout==0 regardless of (val & OCP_READY_MASK) or !(val & OCP_READY_MASK), leading to possible false timeout... Simple correction could be decreasing timeout after checking for !(val & OCP_READY_MASK), not before (Manually converted from email to an actual patch by me. -- JWL) Reported-by: "Juha Leppanen" <juha_motorsportcom@luukku.com> Signed-off-by: "Juha Leppanen" <juha_motorsportcom@luukku.com> Signed-off-by: John W.

2009-12-28mac80211: remove struct ieee80211_if_init_confJohannes Berg
All its members (vif, mac_addr, type) are now available in the vif struct directly, so we can pass that instead of the conf struct. I generated this patch (except the mac80211 and header file changes) with this semantic patch: @@ identifier conf, fn, hw; type tp; @@ tp fn(struct ieee80211_hw *hw, -struct ieee80211_if_init_conf *conf) +struct ieee80211_vif *vif) { <...

2009-12-28mac80211: introduce flush operationJohannes Berg
We've long lacked a good confirmation that frames have really gone out, e.g. before going off-channel for a scan. Add a flush() operation that drivers can implement to provide that confirmation, and use it in a few places: * before scanning sends the nullfunc frames * after scanning sends the nullfunc frames, if any * when going idle, to send any pending frames Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-12-28rtl8187: remove priv->modeJohn W. Linville
It is checked in add_interface, but there it is easily replaced with a check of priv->vif. If that information should become necessary, it is available in vif->type anyway. It is also checked in led_turn_on and led_turn_off, where I made the substitutions as described above. Of course, these checks seem to have been incorrect since the driver was using NL80211_IFTYPE_MONITOR to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED. Anyway, I think these checks may be extraneous...? Signed-off-by: John W. Linville <linville@tuxdriver.com>
