From: Sean Young sean@mess.org Date: Tue, 26 Jun 2018 11:03:18 -0400 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.
