* b43: use pci_is_pcie() instead of obsolete pci_dev.is_pcieBjorn Helgaas2012-05-161-1/+1

* ssb: remove rev from boardinfoHauke Mehrtens2012-05-162-3/+3
| | | | | | | | | | | | | | Previously the rev contained the revision read from the pci config space and was used as board_rev in the wireless drivers. This is wrong the board_rev is only fetched from the sprom accordingly to the open source part of the Broadcom SDK and brcmsmac. This patch removes the rev from the boardinfo structure and uses the board_rev attribute from sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC code.

In 'net' we added a bug fix to make iwlwifi report a more accurate skb->truesize but this conflicted with RX path changes that happened meanwhile in net-next. In e1000e a conflict arose in the validation code for settings of adapter->itr. 'net-next' had more sophisticated logic so that logic was used. Signed-off-by: David S. Miller <davem@davemloft.net>
| * b43: only reload config after successful initializationSeth Forshee2012-04-271-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2a19032 (b43: reload phy and bss settings after core restarts) introduced an unconditional call to b43_op_config() at the end of b43_op_start(). When firmware fails to load this can wedge the system. There's no need to reload the configuration after a failed initialization anyway, so only make the call if initialization was successful.

This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

|/ | | | | | | | | | | | | | | | | This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* b43: Load firmware from a work queue and not from the probe routineLarry Finger2012-03-132-27/+35
| | | | | | | | | | | Recent changes in udev are causing problems for drivers that load firmware from the probe routine. As b43 has such a structure, it must be changed. As this driver loads more than 1 firmware file, changing to the asynchronous routine request_firmware_nowait() would be complicated. In this implementation, the probe routine starts a queue that calls the firmware loading routines. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

* b43: prevent firmware on bcm5354 from taking over wrong GPIO pinsHauke Mehrtens2012-03-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent firmware >= 478.104 it runs out of memory after a very short time in OpenWrt after doing an active scan or any thing else where packages are send. This was cased by a gpio misconfiguration, the firmware triggered the GPIO pins used for buttons on some devices and that caused an other driver (OpenWrt diag) listening for these buttons irqs to send many messages to the user space. This patch fixes the bug for my devices (Asus WL-520GU) and makes it work with firmware 666.2. Now the firmware just uses LED GPIO pin number 1 and not the button pins any more. This is the GPIO Pin layout used on my device, see [0]. GPIO pin layout: pin# name type 0 power led 1 wlan led 2 reset button 3 ses buttom This is the nvram configuration output of "nvram show |grep gpio" related nvram configuration: wl0gpio2=11 wl0gpio3=11 wl0gpio0=11 wl0gpio1=0x02 reset_gpio=2 [0]: https://dev.openwrt.org/browser/trunk/package/broadcom-diag/src/diag.c Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

In such cases packets can not be passed down to the device and are erroneusly dropped by the code.
