2010-07-14ath5k: clean up rxlink handlingBruno Randolf
There were a few places where the sc->rxlink pointer was set to NULL "just in case". This helps nothing - quite to the contrary it is problematic since it can create self-linked rx descriptors in the middle of the list of receive buffers. Here is an example how this could happen (thanks Bob!): cpu 0: cpu 1: ath5k_rx_stop ath5k_tasklet_rx sc->rxlink = NULL; /* just in case */ // following doesn't link used // buffer to prev. ath5k_rxbuf_setup() In the case of ath5k_rx_stop() and ath5k_stop_locked() buffers/descriptors are not changed so rxlink should not be changed as well. In ath5k_intr() we seem to try to work around a hardware bug, as the comment (which is copied 1:1 from the HAL) suggests. I don't see how this could help. Also the HAL does not set rxlink in this case (So where does this code come from? It has been there since the first import of ath5k). Changed to just increment a statistics counter. After this patch rxlink is only set to NULL before we initialize rx descriptors and updated when the descriptors are linked together.

2010-07-14ath5k: disable tasklets during resetBob Copeland
Based on a patch from Bruno Randolf, attempting useful work while we are resetting the chip just leads to interface lockups and bad descriptor data, and possibly DMAing to freed buffers. Let's suspend all tasklets while reprogramming the registers in the card to avoid such problems. In the future we can convert the tasklets to threaded interrupt handlers to simplify things.

2010-07-14ath5k: move reset to mac80211 workqueueBob Copeland
We currently trigger a reset via a tasklet when certain error conditions are detected so that the card will (eventually) restart. Unfortunately this makes locking complicated since reset can also be called in process context (e.g. for channel change). Currently nothing protects against concurrent resets, which can be the source of corruption bugs. Reset takes too long to spinlock the whole thing, so this patch moves deferred resets into the mac80211 workqueue to enable use of sc->lock mutex.

2010-07-14ath9k: another fix for the A-MPDU buffer leakFelix Fietkau
The patch 'ath9k: fix a buffer leak in A-MPDU completion' addressed the issue of running out of buffers/descriptors in the tx path if a STA is deleted while tx status feedback is still pending. The remaining issue is that the skbs of the buffers are not reclaimed, leaving a memory leak. This patch fixes this issue by running the buffers through ath_tx_complete_buf(), ensuring that the pending frames counter is also updated.

2010-07-14hostap_pci: set dev->base_addr during probeJohn W. Linville
"hostap: Protect against initialization interrupt" (which reinstated "wireless: hostap, fix oops due to early probing interrupt") reintroduced Bug 16111. This is because hostap_pci wasn't setting dev->base_addr, which is now checked in prism2_interrupt. As a result, initialization was failing for PCI-based hostap devices. This corrects that oversight.

2010-07-14Input: synaptics - fix wrong dimensions checkTakashi Iwai
The commit 83ba9ea8a04b72dfee2515428c15e7414ba4fc61 ommitted the return line for the old synaptics model accidentally. This resulted in a wrong check, namely, the dimensions are checked for the old devices that don't support the query properly. This patch adds the return line back.

2010-07-14mfd: Fix 88pm860x uninitialized variable and clean upDan Carpenter
The original code had a compile warning: drivers/mfd/88pm860x-core.c:431: warning: ‘ret’ may be used uninitialized in this function It seems like the warning is valid if either pdata or pdata->touch is NULL. This patch checks pdata and pdata->touch at the beginning of the function. That means everything can be pulled in one indent level. Now all the statements fit within the 80 character limit. Also at that point the "use_gpadc" variable isn't needed and removing it simplifies the logic.
