media: atmel-isc: avoid returning a random value at isc_parse_dt()
As warned by smatch: drivers/media/platform/atmel/atmel-isc.c:2097 isc_parse_dt() error: uninitialized symbol 'ret'. The problem here is that of_graph_get_next_endpoint() can potentially return NULL on its first pass, with would make it return a random value, as ret is not initialized. While here, use while(1) instead of for(; ;), as while is the preferred syntax for such kind of loops. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
