Subject: [PATCH] PM: suspend: Set mem_sleep_current during kernel command line setup
Git-commit: 9bc4ffd32ef8943f5c5a42c9637cfd04771d021b
Patch-mainline: v6.9-rc1
References: git-fixes

psci_init_system_suspend() invokes suspend_set_ops() very early during
bootup even before kernel command line for mem_sleep_default is setup.
This leads to kernel command line mem_sleep_default=s2idle not working
as mem_sleep_current gets changed to deep via suspend_set_ops() and never
changes back to s2idle.

Set mem_sleep_current along with mem_sleep_default during kernel command
line setup as default suspend mode.
