Subject: [PATCH AUTOSEL 4.14 19/20] atm: hide unused procfs functions

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit fb1b7be9b16c1f4626969ba4e95a97da2a452b41 ]

When CONFIG_PROC_FS is disabled, the function declarations for some
procfs functions are hidden, but the definitions are still build,
as shown by this compiler warning:

net/atm/resources.c:403:7: error: no previous prototype for 'atm_dev_seq_start' [-Werror=missing-prototypes]
net/atm/resources.c:409:6: error: no previous prototype for 'atm_dev_seq_stop' [-Werror=missing-prototypes]
net/atm/resources.c:414:7: error: no previous prototype for 'atm_dev_seq_next' [-Werror=missing-prototypes]

Add another #ifdef to leave these out of the build.
