6.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 4afcb58ea47e66c025d2b0a5f091dce5aaf95b0f ]
nvmem_cell_read_u32() may return -EPROBE_DEFER if NVMEM supplier has not yet been probed. Future reprobe may succeed, so printing:
i.mx8mm_thermal 30260000.tmu: Failed to read OCOTP nvmem cell (-517).
to the log is confusing. Fix this by using dev_err_probe. This also elevates the message from warning to error, which is more correct: The log message is only ever printed in probe error path and probe aborts afterwards, so it really warrants an error-level message.
