git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux * 'modsplit-Oct31_2011' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: (230 commits) Revert "tracing: Include module.h in define_trace.h" irq: don't put module.h into irq.h for tracking irqgen modules. bluetooth: macroize two small inlines to avoid module.h ip_vs.h: fix implicit use of module_get/module_put from module.h nf_conntrack.h: fix up fallout from implicit moduleparam.h presence include: replace linux/module.h with "struct module" wherever possible include: convert various register fcns to macros to avoid include chaining crypto.h: remove unused crypto_tfm_alg_modname() inline uwb.h: fix implicit use of asm/page.h for PAGE_SIZE pm_runtime.h: explicitly requires notifier.h linux/dmaengine.h: fix implicit use of bitmap.h and asm/page.h miscdevice.h: fix up implicit use of lists and types stop_machine.h: fix implicit use of smp.h for smp_processor_id of: fix implicit use of errno.h in include/linux/of.h of_platform.h: delete needless include <linux/module.h> acpi: remove module.h include from platform/aclinux.h miscdevice.h: delete unnecessary inclusion of module.h device_cgroup.h: delete needless include <linux/module.h> net: sch_generic remove redundant use of <linux/module.h> net: inet_timewait_sock doesnt need <linux/module.h> ... Fix up trivial conflicts (other header files, and removal of the ab3550 mfd driver) in - drivers/media/dvb/frontends/dibx000_common.c - drivers/media/video/{mt9m111.c,ov6650.c} - drivers/mfd/ab3550-core.c - include/linux/dmaengine.h
2011-11-01drivers/dma: Add module.h to files implicitly using it.Paul Gortmaker1-0/+1
Fix files that were implicitly using module.h but not calling it out for inclusion directly. We'll break those once we remove the implicit presence otherwise [With input from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-07-07ARM i.MX dma: Fix burstsize settingsSascha Hauer1-1/+2
dmaengine expects the maxburst parameter in words, not bytes. The imxdma driver and its users do this wrong. Fix this. As a side note the imx-pcm-dma-mx2 driver was 'fixed' to work with imx-dma. This broke the driver with imx-sdma support which correctly takes the maxburst parameter in words. This patch puts the sdma based sound back to work.

2011-01-31dmaengine i.MX dma: initialize dma capabilities outside channel loopSascha Hauer1-3/+3
The capabilities are device specific fields, not channel specific fields. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-10-22dma: imx-dma: fix signedness bugSascha Hauer1-1/+3
mxdmac->channel was unsigned, so check (imxdmac->channel < 0) for failed imx_dma_request_by_prio() made no sence. Explicitly check signed values. Also, fix uninitialzed use of ret.

2010-10-08dmaengine: Add Freescale i.MX1/21/27 DMA driverSascha Hauer1-0/+422
This driver is currently implemented as a user to the old i.MX DMA API. This allows us to convert each user of the old API to the dmaengine API one by one. Once this is done the old DMA driver can be merged into the i.MX dmaengine driver.
