s5p-mfc: Add release callback for memory region devs

2016-08-19T07:51:13Z

commit 6311f1261f59ce5e51fbe5cc3b5e7737197316ac upstream. When s5p_mfc_remove() calls put_device() for the reserved memory region devs, the driver core warns that the dev doesn't have a release callback: WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90 Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed. Also, the declared DMA memory using dma_declare_coherent_memory() isn't relased so add a dev .release that calls dma_release_declared_memory().

s5p-mfc: Set device name for reserved memory region devs

2016-08-19T07:51:13Z

commit 29debab0a94035a390801d1f177d171d014b7765 upstream. The devices don't have a name set, so makes dev_name() returns NULL which makes harder to identify the devices that are causing issues, for example: WARNING: CPU: 2 PID: 616 at drivers/base/core.c:251 device_release+0x8c/0x90 Device '(null)' does not have a release() function, it is broken and must be fixed. And after setting the device name: WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90 Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.

[media] v4l: vsp1: Fix VI6_WPF_SZCLIP_SIZE_MASK macro

2015-10-28T15:38:34Z

commit 03b36e4dcf422a10da8b67bce2ed00b34ec58aac upstream. Clipping size bit of VI6_WPFn _HSZCLIP and VI6_WPFn _VSZCLIP register are from 0 bit to 11 bit. But VI6_WPF_SZCLIP_SIZE_MASK is set to 0x1FFF, this will mask until the reserve bits. This fixes size for VI6_WPF_SZCLIP_SIZE_MASK.

v4l: omap3isp: Fix sub-device power management code

2015-09-30T09:13:08Z

commit 9d39f05490115bf145e5ea03c0b7ec9d3d015b01 upstream. Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour") modified the media controller link setup notification API and updated the OMAP3 ISP driver accordingly. As a side effect it introduced a bug by turning power on after setting the link instead of before. This results in sub-devices not being powered down in some cases when they should be. Fix it.

media: s5p-mfc: fix mmap support for 64bit arch

2015-04-22T06:58:46Z

commit 05b676ab42f624425d5f6519276e506b812fa058 upstream. TASK_SIZE is depends on the systems architecture (32 or 64 bits) and it should not be used for defining offset boundary for mmaping buffers for CAPTURE and OUTPUT queues. This patch fixes support for MMAP calls on the CAPTURE queue on 64bit architectures (like ARM64).
