e4ded64e88 oot: fix mutex unlocking in vrs rtc 
Kernel throws a dump trace upon setting wakealarm time on VRS RTC.
We are unlocking mutex twice in a single API call. Delete one instance
which is not required.

74c0a6d16d drivers: Drop inline from driver remove wrapper 
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.

48061dcb5d rtc: Remove DT check for VRS RTC 
The VRS RTC driver does not required device-tree because the device is
populated by the parent NVIDIA VRS PSEQ driver. Therefore, remove the
device-tree check in the probe function of the VRS RTC driver so that it
is not necessary to populate the device-tree node for the RTC device.

2f9478c1eb rtc: add VRS10 PSEQ RTC driver 
Adding RTC driver support for Nvidia based Voltage Regulator Power
Sequencer. Driver depends on CONFIG_MFD_NVVRS_PSEQ to get enabled which
is a parent driver for RTC. Following are the VRS RTC functionalies:
1. RTC executes alarm function to wake system from suspend/shutdown state.
2. RTC has 32bit time counter register which increments each second.
3. RTC triggers interrupt when the set alarm time becomes equal to the time
read from TIME registers.
