[media] media: s5p-mfc: fix broken pointer cast on 64bit arch

2015-04-01T09:56:56+00:00

Unsigned int cannot be used to store casted pointer on 64bit
architecture, so correct such casts to properly use unsigned long
variables.

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

2015-04-01T09:56:56+00:00

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).

[media] sh_veu: v4l2_dev wasn't set

2015-04-01T09:56:55+00:00

The v4l2_dev field of struct video_device must be set correctly.
This was never done for this driver, so no video nodes were created
anymore.

[media] s5p-mfc: Fix NULL pointer dereference caused by not set q->lock

2015-03-04T11:59:58+00:00

The patch "media: s5p-mfc: use vb2_ops_wait_prepare/finish helper"
(654a731be1a0b6f606f3f3d12b50db08f2ae3c3) introduced a kernel panic.
The q->lock was set for just one queue, the other was not set thus causing
a NULL pointer dereference.

[media] s5p-jpeg: exynos3250: fix erroneous reset procedure

2015-03-04T11:59:34+00:00

The first while loop in the function exynos3250_jpeg_reset had no chance
to be executed because the reg variable was initialized to 0.
Initialize reg variable to 1 to fix the issue.

[media] s5p-tv: hdmi needs I2C support

2015-03-04T11:59:14+00:00

Building the s5p-tv HDMI support when CONFIG_I2C is disabled
gives us this build error:

s5p-tv/hdmi_drv.c: In function 'hdmi_probe':
s5p-tv/hdmi_drv.c:947:2: error: implicit declaration of function 'i2c_get_adapter' [-Werror=implicit-function-declaration]
  adapter = i2c_get_adapter(pdata->hdmiphy_bus);
  ^

This patch changes the Kconfig description to include I2C
as a dependency for this driver, so it cannot be configured
incorrectly.

[media] soc-camera: Fix devm_kfree() in soc_of_bind()

2015-03-03T13:15:48+00:00

Unlike scan_async_group(), soc_of_bind() doesn't allocate its
soc_camera_async_client structure using devm_kzalloc(), but has it
embedded inside the soc_of_info structure.  Hence on failure, it must
free the whole soc_of_info structure, and not just the embedded
soc_camera_async_client structure, as the latter causes a warning, and
may cause slab corruption:

2015-03-02T16:27:11+00:00

The burst length could be BEATS_4/8/16. Before this patch, isi use default
value BEATS_4. To imporve the performance we could set it to BEATS_16.

Otherwise sometime it would cause the ISI overflow error.
