[PATCH] Reflow logic to make it easier to follow
The control flow was:
if (!y) {
ppix = ...
}
if (y) {
...
} else if (x) {
use ppix for something
} else {
use ppix for something
}
Merge the if(!y) block with the two else branches. This avoids
a false-positive in the clang static analyzer, it can't know that
!y and x are mutually exclusive.
The result looks something like this:
if (y) {
...
} else {
ppix = ...
if (x) {

[PATCH xf86-video-nouveau 1/2] xv: Avoid shadowed declaration of 'int i' in NVPutImage
int i is accessed outside immediate scope so leave declaration at
the highest common scope level:
1073: int ret, i;
...
// Highest common scope
...
1193: if (newTTSize <= destination_buffer->size) {
...
// Used in this scope
...
1248: } else {
...
// Used in this scope
...
1316: }

[PATCH] nouveau_xv: Avoid reading off the end of the source image on NV50+
The 'w' argument to NVCopyNV12ColorPlanes is used to index into the
source image. line_len is rounded up to 8 on NV50+, so if the source
image (+ left offset) is not rounded to 8, NVCopyNV12ColorPlanes could
read past the end of the array and crash X. This change can cause the
last few horizontal pixels of dst to not be initialized, but they
should be truncated by the renderer anyways.
