Hi Rabin,

I tried to reproduce the lockup issue with the following change but not 
seeing any lockup issue.
I implement enable/disable for fixed regulator and printed the string as 
enable/disable
During registration I got the log as
[    0.349955] Registering the regulator vbat
[    0.354352] vbat: 3300 mV
[    0.357260] Registering the regulator vtest1
[    0.361810] fixed_enable(): Enabling vtest1
[    0.366144] vtest1: 3300 mV
[    0.369177] vtest1: supplied by vbat
::::::::::::::::

and when init_complete() get called then it happened as

[    1.509855] vtest1: disabling
[    1.512813] fixed_disable(): Disabling vtest1
[    1.517158] fixed_disable(): Disabling vbat
[    1.521342] vbat: disabling
[    1.524124] fixed_disable(): Disabling vbat


Also reviewing the change, I am not seeing any call trace where the 
recursive locking happening.

Please help to reproduce/understand the issue.
