[PATCH v2 6/7] serial: qcom-geni: drop flip buffer WARN()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Drop the unnecessary WARN() in case the TTY buffers are ever full in
favour of a rate limited dev_err() which doesn't kill the machine when
panic_on_warn is set.
