[PATCH 5.12 145/173] phy: cadence: Sierra: Fix error return code in cdns_sierra_phy_probe()

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Wang Wensheng <wangwensheng4@xxxxxxxxxx>

commit 6411e386db0a477217607015e7d2910d02f75426 upstream.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: a43f72ae136a ("phy: cadence: Sierra: Change MAX_LANES of Sierra to 16")
