Subject: [PATCH] media: rc: be less noisy when driver misbehaves
Since commit 48231f289e52 ("media: rc: drivers should produce alternate
pulse and space timing events"), on meson-ir we are regularly producing
errors. Reduce to warning level and only warn once to avoid flooding
the log.
A proper fix for meson-ir is going to be too large for v4.18.
