sirfsoc_dma_prep_cyclic() returns pointer, thus NULL should be used instead of 0 in order to fix the following sparse warning: drivers/dma/sirf-dma.c:598:24: warning: Using plain integer as NULL pointer Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

In mmp pdma, phy channels are allocated/freed dynamically. The mapping from DMA request to DMA channel number in DRCMR should be cleared when a phy channel is freed. Otherwise conflicts will happen when: 1. A is using channel 2 and free it after finished, but A still maps to channel 2 in DRCMR of A. 2. Now another one B gets channel 2. So B maps to channel 2 too in DRCMR of B. In the datasheet, it is described that "Do not map two active requests to the same channel since it produces unpredictable results" and we can observe that during test.

In mmp pdma, phy channels are allocated/freed dynamically and frequently. But no proper protection is added. Conflict will happen when multi-users are requesting phy channels at the same time. Use spinlock to protect. Signed-off-by: Xiang Wang <wangx@marvell.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

In rare cases (mostly for the testing purposes) the dw_dmac driver might be compiled as a module as well as the other LPSS device drivers (I2C, SPI, HSUART). When udev handles the event of the devices appearing the dw_dmac module is missing. This patch will fix that.

This patch fixes sparse warning: drivers/dma/acpi-dma.c:76:21: sparse: cast to restricted __le32 Since everything in all ACPI tables is little-endian, by definition, the used types in practice are uXX. Thus, we have to enforce __leXX if we want to convert them to CPU order.

Pull drm fix from Dave Airlie: "Just a quick fix that a few people have reported, be nice to have in asap" The drm tree seems to be very confused about 64-bit divides. Here it uses a slow 64-by-64 bit divide to divide by a small constant. Oh well. Doesn't look performance-critical, just stupid. * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon: fix 64 bit divide in SI spm code

Commit 46a1c2c7 ("vfs: export lseek_execute() to modules") broke the tmpfs SEEK_DATA/SEEK_HOLE implementation, because vfs_setpos() converts the carefully prepared -ENXIO to -EINVAL.
