Subject: mailbox: bcm-flexrm-mailbox: Fix mask used in CMPL_START_ADDR_VALUE()
From: Anup Patel <anup.patel@xxxxxxxxxxxx>
commit 6d2061b981af165d3e45462e0804b5a1f2f4c7bc upstream.
The mask used in CMPL_START_ADDR_VALUE() should be 27bits instead of
26bits. This incorrect mask was causing completion writes to 40bits
physical address fail.
This patch fixes mask used in CMPL_START_ADDR_VALUE() macro.

ring manager")
