Subject: [PATCH] mfd: sec: Merge separate core and irq modules
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

There is no reason to have these two kernel modules separate. Having
them merged into one kernel module also slightly reduces memory
consumption and module load times a little.

mapped size (lsmod):
         before:             after:
    sec_core   20480    sec_core   24576
    sec_irq    16384
    ----------------
    total      36864

Section sizes (size -A):
         before:             after:
    sec_core    6780    sec_core   13239
    sec_irq     8046
    ----------------
    Total      14826
