X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=350f66d58a62e63ef3163450f68ed4b2a0ab507b;p=linux-beck.git ptp: igb: use helpers for converting ns to timespec. This patch changes the driver to use ns_to_timespec64() and timespec64_to_ns() instead of open coding the same logic. Compile tested only. Signed-off-by: Richard Cochran Signed-off-by: David S.
