| H A D | lirc.h | 72e637fe Fri Oct 30 06:52:30 CDT 2020 Dan Carpenter <dan.carpenter@oracle.com> media: rc: validate that "rc_proto" is reasonable
Smatch complains that "rc_proto" comes from the user and it can result
in shift wrapping in ir_raw_encode_scancode()
drivers/media/rc/rc-ir-raw.c:526 ir_raw_encode_scancode()
error: undefined (user controlled) shift '1 << protocol'
This is true, but I reviewed the surrounding code and it appears
harmless. Anyway, let's verify that "rc_proto" is valid as a kernel
hardening measure.
