[RFC 0/7] eliminate snprintf with overlapping src and dst

From: Rasmus Villemoes

Doing snprintf(buf, len, "%s...", buf, ...) for appending to a buffer
currently works, but it is somewhat fragile, and any other overlap
between source and destination buffers would be a definite bug. This
is an attempt at eliminating the relatively few occurences of this
pattern in the kernel.

I could use another set of eyes on all of these. The drm/amdkfd patch
is unfortunately rather large, but I couldn't find a better way to do
this.

Rasmus Villemoes (7):
drm/amdkfd: avoid fragile and inefficient snprintf use
Input: joystick - avoid fragile snprintf use
leds: avoid fragile sprintf use
drivers/media/pci/zoran: avoid fragile snprintf use
wlcore: avoid fragile snprintf use
[media] ati_remote: avoid fragile snprintf use
USB: usbatm: avoid fragile and inefficient snprintf use
