Subject: [PATCH v4 2/2] drivers/base/memory.c: Rename the misleading parameter
Message-ID: <20190329093659.GG7627@MiWiFi-R3L-srv>

The input parameter 'phys_index' of memory_block_action() is actually
the section number, but not the phys_index of memory_block. This is
a relict from the past when one memory block could only contain one
section.

Rename it to start_section_nr.
