2011-01-13iwmc3200wifi: Return proper error for iwm_if_allocAxel Lin1-0/+2
In the case of alloc_netdev_mq failure and kmalloc failure, current implementation returns ERR_PTR(0). As a result, the caller of iwm_if_alloc does not catch the error by IS_ERR macro. Fix it by setting proper error code for ret variable in the failure cases. Signed-off-by: Axel Lin <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2011-01-10hostap_cs: fix sleeping function called from invalid contextStanislaw Gruszka1-9/+6
pcmcia_request_irq() and pcmcia_enable_device() are intended to be called from process context (first function allocate memory with GFP_KERNEL, second take a mutex). We can not take spin lock and call them. It's safe to move spin lock after pcmcia_enable_device() as we still hold off IRQ until dev->base_addr is 0 and driver will not proceed with interrupts when is not ready. Patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=643758 Reported-and-tested-by: [email protected] Cc: [email protected] # 2.6.34+ Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: John W.

2011-01-10ipw2200: Check for -1 INTA in tasklet too.Indan Zupancic1-0/+7
This is an attempt to fix a long standing open bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334 The interrupt handler checks for INTA being -1, apparently that means that the hardware is gone. But the interrupt handler defers actual interrupt processing to a tasklet. By the time the tasklet is run and checks INTA again, the hardware might be gone and INTA be -1, which confuses the driver because all event bits are set. The patch applies to 2.6.37.

2011-01-10p54: fix sequence no. accounting off-by-one errorChristian Lamparter1-1/+1
P54_HDR_FLAG_DATA_OUT_SEQNR is meant to tell the firmware that "the frame's sequence number has already been set by the application." Whereas IEEE80211_TX_CTL_ASSIGN_SEQ is set for frames which lack a valid sequence number and either the driver or firmware has to assign one. Yup, it's the exact opposite!

Commit "ath9k_hw: Abort rx if hw is not coming out of full sleep in reset" uncondionally added aborting RX DMA in a HW reset, though it is a bit unclear as to why this is needed. Anyway, RX DMA is handled in the target for USB devices, and this would interfere with normal operations (scanning etc.), so fix this.

This patch revamps some common code-paths which are shared between (re-)initialization and suspend/resume subroutines. It also adds some helpful comments about quirks and associated difficulties.

2011-01-04ath9k: fix spur mitigation no-spur case for AR9002Brian Prodoehl1-2/+3
For the AR9002, the spur frequency read from the EEPROM is mangled before being compared against AR_NO_SPUR. This results in the driver trying to set up the spur mitigation for bogus spurs, rather than cleanly breaking out. Signed-off-by: Brian Prodoehl <[email protected]> Signed-off-by: John W.

2011-01-04iwlagn: fix scan tx antenna setting on 5Ghz bandStanislaw Gruszka3-16/+6
Looks that we do not set correctly antennas when scanning on 5Ghz band and when bluetooth is enabled, because priv->cfg->scan_tx_antennas[band] is only defined for IEEE80211_BAND_2GHZ. To fix we check band before limiting antennas to first one. This allow to remove hard coded cfg->scan_tx_antennas[band].

2011-01-04iwlagn: enable only rfkill interrupt when device is downStanislaw Gruszka2-4/+11
Since commit 6cd0b1cb872b3bf9fc5de4536404206ab74bafdd "iwlagn: fix hw-rfkill while the interface is down", we enable interrupts when device is not ready to receive them. However hardware, when it is in some inconsistent state, can generate other than rfkill interrupts and crash the system. I can reproduce crash with "kernel BUG at drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing firmware restarts. To fix only enable rfkill interrupt when down device and after probe. I checked patch on laptop with 5100 device, rfkill change is still passed to user space when device is down.
