Hi All,
I was working with a USB camera. As soon as I plug it into the host,
it probes and video device node gets created with the following

All,
ALSA has to make media_entity_pipeline_start() call in irq
path. I am seeing warnings that the graph_mutex is unsafe irq
lock as expected. We have to update MC start/stop pipeline
to be irq safe for ALSA. Maybe there are other MC interfaces
that need to be irq safe, but I haven't seen any pro

Convert omap_vout_uservirt_to_phys() to use get_vaddr_pfns() instead of
hand made mapping of virtual address to physical address. Also the
function leaked page reference from get_user_pages() so fix that by
properly release the reference when omap_vout_buffer_release() is
called.

Provide simple helper functions to map virtual address range into an

Provide new function get_vaddr_frames(). This function maps virtual
addresses from given start and fills given array with page frame numbers of
the corresponding pages. If given start belongs to a normal vma, the function
grabs reference to each of the pages to pin them in memory.

Currently vb2 core acquires mmap_sem just around call to
__qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix

longer have to drop queue mutex before acquiring mmap_sem. So push

Convert g2d_userptr_get_dma_addr() to pin pages using get_vaddr_frames().
This removes the knowledge about vmas and mmap_sem locking from exynos
