<content type='text'>
There is a typo in the message. The clock name should be 'pclk_ddr_mon'.
Fix it.

While at it, switch to dev_err_probe() which is less verbose, filters
-EPROBE_DEFER, and log the error code in a human readable way.

<content type='text'>
If the regulator_get_optional()	call for the SRAM regulator returns
a probe deferral, we must bail out and retry probing later: failing
to do this will	produce	unstabilities on platforms requiring the
handling for this regulator.

interconnect changes for 5.20

Here are the interconnect changes for the 5.20-rc1 merge window consisting
of two new drivers, misc driver improvements and new device managed API.

 Core change:
- Add device managed bulk API

 Driver changes:
- New driver for NXP i.MX8MP platforms
- New driver for Qualcomm SM6350 platforms
- Multiple bucket support for Qualcomm RPM-based drivers.

There are 4 warnings there:

	drivers/devfreq/devfreq.c:717: warning: Function parameter or member 'ptr' not described in 'qos_max_notifier_call'

It turns that neither val nor ptr are actually used on those
function, so document as such.
