* [media] omap_vout: Added check in reqbuf & mmap for buf_size allocationVaibhav Hiremath2011-07-011-0/+16
| | | | | | | | | | | | | | | | The usecase where, user allocates small size of buffer through bootargs (video1_bufsize/video2_bufsize) and later from application tries to set the format which requires larger buffer size, driver doesn't check for insufficient buffer size and allows application to map extra buffer. This leads to kernel crash, when user application tries to access memory beyond the allocation size. Added check in both mmap and reqbuf call back function, and return error if the size of the buffer allocated by user through bootargs is less than the S_FMT size.

* [media] OMAP_VOUT: Change hardcoded device node number to -1Vaibhav Hiremath2011-07-011-1/+1
| | | | | | | | | | With addition of media-controller framework, now we have various device nodes (/dev/videoX) getting created, so hardcoding minor number in video_register_device() is not recommended. So let V4L2 framework choose free minor number for the device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] OMAP_VOUTLIB: Fix wrong resizer calculationVladimir Pantelic2011-07-011-3/+3
| | | | | | | | | | | The omap_vout_new_crop() function has possible bug, uses uninitialized variable "crop.width/height" which is actually output of the function. Instead we should be using "try_crop.width/height" to calculate the resizer value.
