[PATCH] pcp_clock: return EOPNOTSUPP if !CONFIG_PTP_1588_CLOCK

pcp_clock_register() is checked with IS_ERR(), and will crash if !PTP, change return value to ERR_PTR(-EOPNOTSUPP) for the !CONFIG_PTP_1588_CLOCK and so question resolved. Signed-off-by: Wang Qing --- include/linux/ptp_clock_kernel.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -
