[PATCH 2/4] atm: hide unused procfs functions

From: Arnd Bergmann
Date: Tue May 16 2023 - 15:46:45 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

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.
