2008-11-30input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playbackArjan van de Ven
ml_ff_playback() uses spin_(un)lock_bh. However this function is called with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196. This is not permitted, and will result in a WARN_ON in the bottom half handling code. This patch changes this function to just use spin_lock_irqsave() instead, solving the problem and simplifying the locking logic.

2008-11-30tricky one: hisax sectionsAl Viro
a) hisax_init_pcmcia() needs to be defined only if we have CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared __devinit. b) HiSax_inithardware() can go __init c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card(): checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card); The problem with it is that * hisax_cs_setup_card() is __devinit * hisax_register() is not * hisax_cs_setup_card() is a switch from hell, calling a lot of setup_some_weirdcard() depending on card->typ. _These_ are also __devinit. However, in hisax_register() we have card->typ equal to ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind all that crap, just do nothing and return 2". So we add a trimmed-down callback doing just that and passed to checkcard() by hisax_register(). _This_ is non-init (we can stand the impact on .text size).

2008-11-30advansys fix on ISA-less configsAl Viro
The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

2008-11-19USB: fix SB700 usb subsystem hang bugAndiry Xu
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid USB subsystem hang symptom. The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.

2008-11-19lcd: fix oops if driver only interested in .set_powerBen Dooks
The LCD driver core calls LCD drivers when either the blanking state or the display mode has changed, but does not make any check to see if the called driver has a .set_mode method. This means if a driver only has a .set_power method then the system will OOPS on changing mode (and with the console semaphore held so you cannot easily see the problem). Fix the problem by ensuring that either callback is valid before use.

2008-11-19pxa2xx_spi: bugfix full duplex dma data corruptionNed Forrester
Fixes a data corruption bug in pxa2xx_spi.c when operating in full duplex mode with DMA and using buffers that overlap. SPI transmit and receive buffers are allowed to be the same or to overlap. However, this driver fails if such overlap is attempted in DMA mode because it maps the rx and tx buffers in the wrong order. By mapping DMA_FROM_DEVICE (read) before DMA_TO_DEVICE (write), it invalidates the cache before flushing it, thus discarding data which should have been transmitted. The patch corrects the order of mapping. This bug exists in all versions of pxa2xx_spi.c; similar bugs are in the drivers for two other SPI controllers (au1500, imx). A version of this patch has been tested on kernel 2.6.20 using verification of loopback data with: random transfer length, random bits-per-word, random positive offsets (both larger and smaller than transfer length) between the start of the rx and tx buffers, and varying clock rates.
