Subject: [PATCH 1/1] V4L: stk11xx, add a new webcam driver
Hi,
is it possible to have this driver in the -mm tree for testing purposes until
v4l library will be developped and image resize with bayer->rgb conversion
will be moved there? (Then, I'll push it through v4l people.)
--
stk11xx, add a new webcam driver
Adds support for stk1125, stk1135 and stkdcnew webcam built-in some
notebooks.
