I am reading v4l2 tuner part code these days, when I come to mt20xx.c,
in microtune_init(), the use of the char pointer name maybe cause some
fatal error sometimes for this state:
You mean all the c compilers will give 'unknown' a special process???

Huh?
I mean:
{
char *name = unknown;
and
{
char *name;

name = unknown;
are equivalent.

while pointer name doesn't have its memory.
Don't you confuse
char *foo = bar;
with
char *foo;
strcpy(foo, bar);
?
The first needs *no* runtime memory allocation, as it was pointed out.
The second does need runtime memory
