Hi Greg, After merging the staging tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/staging/rtl8821ae/regd.c: In function '_rtl_reg_apply_beaconing_flags': drivers/staging/rtl8821ae/regd.c:200:20: error: 'IEEE80211_CHAN_NO_IBSS' undeclared (first use in this function) ch->flags &= ~IEEE80211_CHAN_NO_IBSS; ^ drivers/staging/rtl8821ae/regd.c:200:20: note: each undeclared identifier is reported only once for each function it appears in drivers/staging/rtl8821ae/regd.c:204:11: error: 'IEEE80211_CHAN_PASSIVE_SCAN' undeclared (first use in this function) ~IEEE80211_CHAN_PASSIVE_SCAN; ^ drivers/staging/rtl8821ae/regd.c: In function '_rtl_reg_apply_active_scan_flags': drivers/staging/rtl8821ae/regd.c:237:19: error: 'IEEE80211_CHAN_PASSIVE_SCAN' undeclared (first use in this function) if (ch->flags & IEEE80211_CHAN_PASSIVE_SCAN) ^ drivers/staging/rtl8821ae/regd.c: In function '_rtl_reg_apply_radar_flags': drivers/staging/rtl8821ae/regd.c:312:8: error: 'IEEE80211_CHAN_NO_IBSS' undeclared (first use in this function) IEEE80211_CHAN_NO_IBSS | ^ drivers/staging/rtl8821ae/regd.c:313:8: error: 'IEEE80211_CHAN_PASSIVE_SCAN' undeclared (first use in this function) IEEE80211_CHAN_PASSIVE_SCAN; ^ drivers/staging/rtl8821ae/regd.c: In function '_rtl_regd_init_wiphy': drivers/staging/rtl8821ae/regd.c:410:18: error: 'WIPHY_FLAG_CUSTOM_REGULATORY' undeclared (first use in this function) wiphy->flags |= WIPHY_FLAG_CUSTOM_REGULATORY; ^ drivers/staging/rtl8821ae/regd.c:411:19: error: 'WIPHY_FLAG_STRICT_REGULATORY' undeclared (first use in this function) wiphy->flags &= ~WIPHY_FLAG_STRICT_REGULATORY; ^ drivers/staging/rtl8821ae/regd.c:412:19: error: 'WIPHY_FLAG_DISABLE_BEACON_HINTS' undeclared (first use in this function) wiphy->flags &= ~WIPHY_FLAG_DISABLE_BEACON_HINTS; ^ drivers/staging/rtl8821ae/base.c: In function '_rtl_init_mac80211': drivers/staging/rtl8821ae/base.c:372:4: error: 'struct ieee80211_hw' has no member named 'channel_change_time' hw->channel_change_time = 100; ^ drivers/staging/rtl8821ae/base.c: In function 'rtl_beacon_statistic': drivers/staging/rtl8821ae/base.c:1185:2: error: implicit declaration of function 'compare_ether_addr' [-Werror=implicit-function-declaration] if (compare_ether_addr(hdr->addr3, rtlpriv->mac80211.bssid)) ^ drivers/staging/rtl8821ae/ps.c: In function 'rtl_swlps_beacon': drivers/staging/rtl8821ae/ps.c:530:2: error: implicit declaration of function 'compare_ether_addr' [-Werror=implicit-function-declaration] if (compare_ether_addr(hdr->addr3, rtlpriv->mac80211.bssid)) ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c: In function 'rtl8812ae_dm_txpwr_track_set_pwr': drivers/staging/rtl8821ae/rtl8821ae/dm.c:1476:5: warning: array subscript has type 'char' [-Wchar-subscripts] rtl_set_bbreg(hw, RA_TXSCALE, 0xFFE00000, rtl8812ae_txscaling_table[final_ofdm_swing_index]); ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c:1525:5: warning: array subscript has type 'char' [-Wchar-subscripts] rtl_set_bbreg(hw, RB_TXSCALE, 0xFFE00000, rtl8812ae_txscaling_table[final_ofdm_swing_index]); ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c: In function 'rtl8821ae_dm_txpwr_track_set_pwr': drivers/staging/rtl8821ae/rtl8821ae/dm.c:2113:5: warning: array subscript has type 'char' [-Wchar-subscripts] rtl_set_bbreg(hw, RA_TXSCALE, 0xFFE00000, rtl8812ae_txscaling_table[final_ofdm_swing_index]); ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c: In function 'rtl8821ae_dm_check_edca_turbo': drivers/staging/rtl8821ae/rtl8821ae/dm.c:2656:3: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'u64' [-Wformat=] RT_TRACE(COMP_TURBO, DBG_LOUD, ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c:2658:3: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'u64' [-Wformat=] RT_TRACE(COMP_TURBO, DBG_LOUD, ^ drivers/staging/rtl8821ae/rtl8821ae/trx.c: In function '_rtl8821ae_translate_rx_signal_stuff': drivers/staging/rtl8821ae/rtl8821ae/trx.c:461:7: error: implicit declaration of function 'compare_ether_addr' [-Werror=implicit-function-declaration] (!compare_ether_addr(mac->bssid, (fc & IEEE80211_FCTL_TODS) ? ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c: In function 'rtl8821ae_dm_clear_txpower_tracking_state': drivers/staging/rtl8821ae/rtl8821ae/dm.c:487:31: warning: iteration 2u invokes undefined behavior [-Waggressive-loop-optimizations] rtldm->bb_swing_idx_ofdm[p] = rtldm->default_ofdm_index; ^ drivers/staging/rtl8821ae/rtl8821ae/dm.c:485:2: note: containing loop for (p = RF90_PATH_A; p < MAX_RF_PATH; ++p) { ^ Caused by commit 3c05bedb5fef ("Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver"). Did you really want to merge a new driver right now, not wait until after the merge window? I have disabled that driver for today using this patch: From: Stephen Rothwell Date: Fri, 24 Jan 2014 12:57:38 +1100 Subject: [PATCH] Staging: rtl8812ae: disable due to build errors Signed-off-by: Stephen Rothwell --- drivers/staging/rtl8821ae/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/staging/rtl8821ae/Kconfig b/drivers/staging/rtl8821ae/Kconfig index 2aa5dac2f1df..a432e1aa7405 100644 --- a/drivers/staging/rtl8821ae/Kconfig +++ b/drivers/staging/rtl8821ae/Kconfig @@ -2,6 +2,7 @@ config R8821AE tristate "RealTek RTL8821AE Wireless LAN NIC driver" depends on PCI && WLAN depends on m + depends on BROKEN select WIRELESS_EXT select WEXT_PRIV select EEPROM_93CX6 -- 1.8.5.3 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
