From
Subject[PATCH] block: Add default switch case to blk_pm_allow_request() to kill warning
Date
With gcc 4.9.0:

block/blk-core.c: In function 'blk_pm_allow_request':
block/blk-core.c:2607:2: warning: enumeration value 'RPM_ACTIVE' not handled in switch [-Wswitch]
switch (rq->q->rpm_status) {
^

Convert the return statement below the switch() block into a default
case to fix this.

Fixes: e4f36b249b4d4e75 ("block: fix peeking requests during PM")
