V4L/DVB (7235): tuner-simple: fix a buffer overflow
simple_set_tv() creates a buffer with 4 elements, and calls
simple_std_setup(), passing &buffer[1]. This makes the 5th element of buffer to
be initialized to 0, overriding some area outside the buffer.
Also, simple_std_setup() receives a buffer as parameter, but the buffer is
just overriden after the call, so, it doesn't make much sense to pass it as a
parameter.
This patch removes buffer[] from the function call, creating, instead, a local
var to be used internally.
Thanks to Axel Rometsch <axel.rometsch@freenet.de> for pointing the issue.
