Thanks Roel,

Current 2.6.29 ready code doesn't have this bug as the driver is
reworked. It's there in the 2.6.28 code but shouldn't pose a problem
as the err variable should normally evaluate itself to 0 which is
inverted to true (== 1?) thus as (1 < len) is evaluated to true the
statement should work as intended. I don't have hardware supporting
the s5k4aa but I replicated the bug with my ov9650 sensor code and
it still worked as intended.

Summary: Mauro, If you want to add this fix for 2.6.28, go ahead but
 the current code 2.6.28 shouldn't prevent the driver from working
as intended. This is not an issue in the current gspca-m5602 tree.

Regards,
Erik
