irda: off by one
This is an off by one. We would go past the end when we NUL terminate the "value" string at end of the function. The "value" buffer is allocated in irlan_client_parse_response() or irlan_provider_parse_command(). CC: stable@kernel.org Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S.
