media: cec/core: clarify rx-arb-lost usage message
The rx-arb-lost error injection command only works with <op> set to 'any'. Explicitly say so in the usage message. Also use [] to indicate that the <poll> argument is optional. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
