[PATCH] drivers/base/memory.c: remove an unnecessary check on NR_MEM_SECTIONS

From: Wei Yang
Date: Fri Nov 23 2018 - 17:29:04 EST


In commit cb5e39b8038b ("drivers: base: refactor add_memory_section() to
add_memory_block()"), add_memory_block() is introduced, which is only
invoked in memory_dev_init().

When combine these two loops in memory_dev_init() and
add_memory_block(), they looks like this:

for (i = 0; i < NR_MEM_SECTIONS; i += sections_per_block)
for (j = i;
(j < i + sections_per_block) && j < NR_MEM_SECTIONS;
j++)

Since it is sure (i < NR_MEM_SECTIONS) and j sits in its own memory
block, the check of (j < NR_MEM_SECTIONS) is not necessary.

This patch just removes this check.
