    Subject[PATCH 4.18 071/123] b43/leds: Ensure NUL-termination of LED name string
    Date
    4.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Michael Buesch <m@bues.ch>

    commit 2aa650d1950fce94f696ebd7db30b8830c2c946f upstream.

    strncpy might not NUL-terminate the string, if the name equals the buffer size.
    Use strlcpy instead.
