2009-12-21drivers/net/wireless: Correct code taking the size of a pointerJulia Lawall
sizeof(iv16) and sizeof(iv32) are the sizes of pointers. Change them to the size of the copied data. Furthermore, iveiv_entry is a local structure that has just been initialized and is not visible outside this function. Thus, there would seem to be no point to copy data into it. The order of the arguments is thus changed to copy the data into the parameters, which are provided as pointers, suggesting in this case that they should be used to return values. A simplified version of the semantic patch that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2009-12-21ath9k: Last fix for TX software padding.Benoit Papillault
First, we copy/paste the padding stuff from ath9k_tx to ath_tx_cabq since it needs to same kind of padding, but for internally generated beacons. Next, software padding done on TX needs to be removed before calling ieee80211_tx_status. The code was already there in ath_tx_complete but it was wrong. Fix it by using ath9k_cmn_padpos. This later code has been tested by sending packets to a monitor interface and reading packets from the same interface.

2009-12-21iwlwifi: power up all devices for EEPROM readReinette Chatre
Recent commits "iwlwifi: remove power-wasting calls to apm_ops.init()" and "iwlagn: power up device before initializing EEPROM" had the goal of reducing device power consumption from the time the module is loaded until the interface is brought up and the device's power saving mechanisms kick in. The idea is that once the module is loaded there is no need for the device to consume power until the interface is brought up. With the current solution the device is only powered up during EEPROM read, and then so also only if the EEPROM type is OTP. We have found that on certain platforms even non-OTP devices require power to be up during EEPROM read. On these platforms the driver never loads and the system log contains the following: iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080403D8 We thus now power up all devices during EEPROM read. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-12-21iwlwifi: allocated rx page accounting cleanupZhu Yi
In iwlwifi, priv->alloc_rxb_page is used to keep track of the Rx pages allocated by the driver. This cleans up the page free routines by introducing __iwl_free_pages/iwl_free_pages so that the accounting is more accurate and less error prone. This also fixes two instances where the counter was not updated. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-12-21x86/amd-iommu: Fix initialization failure panicJoerg Roedel
The assumption that acpi_table_parse passes the return value of the hanlder function to the caller proved wrong recently. The return value of the handler function is totally ignored. This makes the initialization code for AMD IOMMU buggy in a way that could cause a kernel panic on initialization. This patch fixes the issue in the AMD IOMMU driver.

2009-12-21dma-debug: Do not add notifier when dma debugging is disabled.Shaun Ruffell
If CONFIG_HAVE_DMA_API_DEBUG is defined and "dma_debug=off" is specified on the kernel command line, when you detach a driver from a device you can cause the following NULL pointer dereference: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<c0580d35>] dma_debug_device_change+0x5d/0x117 The problem is that the dma_debug_device_change notifier function is added to the bus notifier chain even though the dma_entry_hash array was never initialized. If dma debugging is disabled, this patch both prevents dma_debug_device_change notifiers from being added to the chain, and additionally ensures that the dma_debug_device_change notifier function is a no-op.

2009-12-21ALSA: fix incorrect rounding direction in snd_interval_ratnum()Krzysztof Helt
The direction of rounding is incorrect in the snd_interval_ratnum() It was detected with following parameters (sb8 driver playing 8kHz stereo file): - num is always 1000000 - requested frequency rate is from 7999 to 7999 (single frequency) The first loop calculates div_down(num, freq->min) which is 125. Thus, a frequency range's minimum value is 1000000 / 125 = 8000 Hz. The second loop calculates div_up(num, freq->max) which is 126 The frequency range's maximum value is 1000000 / 126 = 7936 Hz. The range maximum is lower than the range minimum so the function fails due to empty result range. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-12-21ALSA: HDA: add powersaving hook for RealtekHector Martin
The current Realtek code makes no specific provision for turning stuff off. The codec chip is placed into low-power mode generically, but this doesn't turn off any external hardware connected to it, in particular external amplifiers. This patch creates a hook function that is called by the codec suspend/resume functions. It ought to disable any external hardware in a device-specific way. I've implemented a generic ALC889 function that sets the EAPD pin properly, and used it for the Acer Aspire 8930G which can benefit from this feature. On my laptop, this results in ~0.5W extra savings. Signed-off-by: Hector Martin <hector@marcansoft.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-12-21PM: Use pm_runtime_put_sync in system resumeAlan Stern
This patch (as1317) fixes a bug in the PM core. When a device is resumed following a system sleep, the core decrements the device's runtime PM usage counter but doesn't issue an idle notification if the counter reaches 0. This could prevent an otherwise unused device from being runtime-suspended again after the system sleep. The fix is to call pm_runtime_put_sync() instead of pm_runtime_put_noidle().

2009-12-20pata_cmd64x: fix overclocking of UDMA0-2 modesBartlomiej Zolnierkiewicz
adev->dma_mode stores the transfer mode value not UDMA mode number so the condition in cmd64x_set_dmamode() is always true and the higher UDMA clock is always selected. This can potentially result in data corruption when UDMA33 device is used, when 40-wire cable is used or when the error recovery code decides to lower the device speed down. The issue was introduced in the commit 6a40da0 ("libata cmd64x: whack into a shape that looks like the documentation") which goes back to kernel 2.6.20.
