Subject: [PATCH 5.16 217/227] soc: aspeed: lpc-ctrl: Block error printing on probe defer cases

From: Jae Hyun Yoo <jae.hyun.yoo@...ux.intel.com>

[ Upstream commit 301a5d3ad2432d7829f59432ca0a93a6defbb9a1 ]

Add a checking code when it gets -EPROBE_DEFER while getting a clock
resource. In this case, it doesn't need to print out an error message
because the probing will be re-visited.
