[PATCH] random: move random_min_urandom_seed into CONFIG_SYSCTL ifdef block

From: Fabio Estevam
Date: Tue Jan 31 2017 - 11:37:30 EST


Building arm allnodefconfig causes the following build warning:

drivers/char/random.c:318:12: warning: 'random_min_urandom_seed' defined but not used [-Wunused-variable]

Fix the warning by moving 'random_min_urandom_seed' declaration inside
the CONFIG_SYSCTL ifdef block, where it is actually used.

While at it, remove the comment prior to the variable declaration.
