drm/vmwgfx: Set dmabuf_size when vmw_dmabuf_init is successful

2018-05-30T05:52:42+00:00

commit 91ba9f28a3de97761c2b5fd5df5d88421268e507 upstream. SOU primary plane prepare_fb hook depends upon dmabuf_size to pin up BO (and not call a new vmw_dmabuf_init) when a new fb size is same as current fb. This was changed in a recent commit which is causing page_flip to fail on VM with low display memory and multi-mon failure when cycle monitors from secondary display.

pinctrl: mcp23s08: spi: Fix regmap debugfs entries

2018-05-30T05:52:41+00:00

[ Upstream commit 9b3e4207661e67f04c72af15e29f74cd944f5964 ] The SPI version of this chip allows several devices to be present on the same SPI bus via a local address. If this is in action and if the kernel has debugfs, however, the code attempts to create duplicate entries for the regmap's debugfs: mcp23s08 spi1.1: Failed to create debugfs directory This patch simply assigns a local name matching the device logical address to the `struct regmap_config`. No changes are needed for MCP23S18 because that device does not support any logical addressing. Similarly, I2C devices do not need any action, either, because they are already different in their I2C address. A similar problem is present for the pinctrl debugfs instance, but that one is not addressed by this patch.

Without this patch driver occasionally reinitializes structures too quickly to communicate with firmware after EMP reset causing AdminQ to timeout.

drm/rockchip: Respect page offset for PRIME mmap calls

2018-05-30T05:52:39+00:00

[ Upstream commit 57de50af162b67612da99207b061ade3239e57db ] When mapping external DMA-bufs through the PRIME mmap call, we might be given an offset which has to be respected. However for the internal DRM GEM mmap path, we have to ignore the fake mmap offset used to identify the buffer only. Currently the code always zeroes out vma->vm_pgoff, which breaks the former. This patch fixes the problem by moving the vm_pgoff assignment to a function that is used only for GEM mmap path, so that the PRIME path retains the original offset.
