| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: Hans Verkuil <hverkuil@xs4all.nl>
The msp3430G and msp3435G models cannot do Automatic Standard Detection, so these should be forced to BTSC. These chips are early production versions for the msp34xxG series and are quite rare.
The workaround for kernel 2.6.18 is to use 'standard=32' as msp3400 module option.
