iwlagn: avoid sleep in softirq context
__ieee80211_tasklet_handler -> __ieee80211_rx -> __ieee80211_rx_handle_packet -> ieee80211_invoke_rx_handlers -> ieee80211_rx_h_decrypt -> ieee80211_crypto_tkip_decrypt -> ieee80211_tkip_decrypt_data -> iwl4965_mac_update_tkip_key -> iwl_scan_cancel_timeout -> msleep Ooops! Avoid the sleep by changing iwl_scan_cancel_timeout with iwl_scan_cancel and simply returning on failure if the scan persists. This will cause hardware decryption to fail and we'll handle a few more frames with software decryption. Signed-off-by: John W. Linville <linville@tuxdriver.com>
