3.16.7-ckt12 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Hans de Goede <[email protected]> commit 8e779c6c4a398763c21371fe40f649206041dc1e upstream. Testing has shown that ASM1053 devices do not work properly with transfers larger than 240 sectors, so set max_sectors to 240 on these.
