2015-04-17dmaengine: usb-dmac: Fix dereferencing freed memory 'desc'Yoshihiro Shimoda1-2/+2
This patch fixes an issue that the usb_dmac_desc_free() is dereferencing freed memory 'desc' because it uses list_for_each_entry(). This function should use list_for_each_entry_safe().

2015-04-02dmaengine: usb-dmac: Add Renesas USB DMA Controller (USB-DMAC) driverYoshihiro Shimoda3-0/+920
This DMAC is Renesas USB high-speed module DMA controller that supports slave transfer. This USB-DMAC has similar register sets with R-Car Gen2 DMAC, but the USB-DMAC has specific registers to control the USB transactions. If this code is added into the rcar-dmac driver, it will become unreadable. So, this driver is independent from the rcar-dmac. And, this USB-DMAC uses virt-dma infrastructure.

2015-04-01dmaengine: edma: fixed wrongly initialized data parameter to the edma callbackPetr Kulhavy1-1/+1
The "data" parameter passed indirectly to the edma_callback() should be edma_chan and not the dma_chan. This bug was so far harmless since the offset of struct dma_chan within struct edma_chan is 0. However as soon as someone changes struct edma_chan this would cause troubles.

2015-04-01dmaengine: ste_dma40: fix implicit conversionStefan Agner1-2/+4
The function d40_prep_sg takes the type enum dma_transfer_direction as second last parameter. However, the memcpy calls pass DMA_NONE which is of type enum dma_data_direction. Fix this by passing the actual transfer direction DMA_MEM_TO_MEM. This does not change the actual code flow since only the transfer direction DMA_MEM_TO_DEV and DMA_DEV_TO_MEM are actually used in the function d40_prep_sg.

This patch adds a driver for the DMA controller found in the Ingenic JZ4780. It currently does not implement any support for the programmable firmware feature of the controller - this is not necessary for most uses. It also does not take priority into account when allocating channels, it just allocates the first available channel. This can be implemented later.

.. after extensive statistical analysis of my G+ polling, I've come to the inescapable conclusion that internet polls are bad. Big surprise. But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38% margin, in a poll that people weren't even supposed to participate in. Who can argue with solid numbers like that? 5,796 votes from people who can't even follow the most basic directions? In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%, but with a total of 29,110 votes right now. Now, arguably, that vote spread is only about 3,200 votes, which is less than the almost six thousand votes that the "please ignore" poll got, so it could be considered noise. But hey, I asked, so I'll honor the votes.

2015-02-22debugfs: leave freeing a symlink body until inode evictionAl Viro1-17/+17
As it is, we have debugfs_remove() racing with symlink traversals. Supply ->evict_inode() and do freeing there - inode will remain pinned until we are done with the symlink body. And rip the idiocy with checking if dentry is positive right after we'd verified debugfs_positive(), which is a stronger check...
