ENGR00143341-1 ldb: return error if ldb driver is not enabled
On mx53 QS board, set boot option as "console=ttymxc0,115200 root=
/dev/nfs ip=dhcp nfsroot=x.x.x.x:/nfs/rootfs". Run "echo mem >
/sys/power/state" and then press power key to resume. The following
error is reported:
ffe0: 00000000 7efcc5e0 2ab33c48 2ab8624c 60000010 00000001 ddffdb57 e735e8fd
[<8020ad6c>] (ldb_enable+0x28/0x298) from [<8020b058>] (ldb_resume+0x7c/0x88)
[<8020b058>] (ldb_resume+0x7c/0x88) from [<8023ed0c>]
(platform_pm_resume+0x40/0x4c)
[<8023ed0c>] (platform_pm_resume+0x40/0x4c) from [<802412f4>] (pm_op+0xac/0x118)
To fix above error, return -ENODEV if the ldb driver is not enabled.
