X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3359e7c2e904eac4e76d5b8b5e9390a622863df8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ptp: gianfar: 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. Signed-off-by: Richard Cochran Signed-off-by: David S.
