Subject: [PATCH] introduce-samsung-camera-unit-driver.patch
|
|
|
|
This is the kernel side of an old (2004) samsung camera driver for 2440
|
|
It doesn't compile on modern kernel yet, this patch introduces it into the
|
|
kernel tree without gross mods, so it is broken code we can start to work on
