4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <a...@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")
