Subject: [PATCH -next] platform/x86/dell-wmi-sysman: Make some symbols static

Fix the following sparse warnings:

drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:38:23:
warning: symbol 'po_is_pass_set' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:70:23: warning:
symbol 'po_current_password' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:99:23:
warning: symbol 'po_new_password' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:103:23:
warning: symbol 'po_min_pass_length' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:107:23:
warning: symbol 'po_max_pass_length' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:116:23:
warning: symbol 'po_mechanism' was not declared. Should it be static?
drivers/platform/x86/dell-wmi-sysman/passobj-attributes.c:129:23:
warning: symbol 'po_role' was not declared. Should it be static?

po_is_pass_set, po_current_password, po_new_password,
po_min_pass_length, po_max_pass_length, po_mechanism and po_role
have only call within passobj-attributes.c
They should be static

I think at the same time you may put all of them in a way that each
occupies only a single line.
