vzalloc combines vmalloc and memset 0.
The Coccinelle semantic patch used to make this change is as follows:

if (!d) S

dropped frames. gPTP gives you a central reference to time.
When such a long message is required, it means that we do

This adds the HDMI CEC keymap module.
This patch depends on these two patches:
https://patchwork.linuxtv.org/patch/34675/
https://patchwork.linuxtv.org/patch/34679/
So those two have to be merged in mainline before this patch can be
merged.

The callback function dma_buf_describe() returns an int not void so the
function pointer cast in dma_buf_show() is wrong. dma_buf_describe() can
also fail when acquiring the mutex gets interrupted so always returning
0 in dma_buf_show() is wrong, too.
Fix both issues by avoiding the indirection vi
There is only a single user of dma_buf_debugfs_create_file() and that
one got the function pointer cast wrong. With that one fixed, there is
no need to have a wrapper for debugfs_create_file(), just call it
directly.
With no users left, we can remove dma_buf_debugfs_create_file().
While at it, si
Change the error handling in dma_buf_init_debugfs() to remove the
"dma_buf" directory if creating the "bufinfo" file fails. No need to
have an empty debugfs directory around.

This small series is the v2 of the patch posted initially here:

It not only fixes the type mix-up and addresses Daniel's remark (patch 1),
it also smoothes out the error handling in dma_buf_init_debugfs() (patch 2)
and removes the then unn
Hello everyone,
I've been doing some latency testing on my sur40 driver, and I've
measured over 160 ms of round-trip delay (with an external high-speed
camera, delay between lighting up an LED and seeing the on-screen
response in the video stream).
I'm aware that this value has to factor in scree
