    Subject[PATCH 4.10 095/111] cpsw/netcp: cpts depends on posix_timers
    Date
    4.10-stable review patch.  If anyone has any objections, please let me know.

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

    From: Arnd Bergmann <arnd@arndb.de>

    commit 07fef3623407444e51c12ea57cd91df38c1069e0 upstream.

    With posix timers having become optional, we get a build error with
    the cpts time sync option of the CPSW driver:

    drivers/net/ethernet/ti/cpts.c: In function 'cpts_find_ts':
    drivers/net/ethernet/ti/cpts.c:291:23: error: implicit declaration of function 'ptp_classify_raw';did you mean 'ptp_classifier_init'? [-Werror=implicit-function-declaration]

    This adds a hard dependency on PTP_CLOCK to avoid the problem, as
    building it without PTP support makes no sense anyway.

    Fixes: baa73d9e478f ("posix-timers: Make them configurable")
