-stable review patch. If anyone has any objections, please let us know.
------------------
From: Hans Verkuil <[email protected]>
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.
