5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
commit b5ea08aa883da05106fcc683d12489a4292d1122 upstream.
Clocks acquired with of_clk_get() need to be freed with clk_put(). Call
clk_put() on priv->clks[0] on error path.
Fixes: 3df0e240caba ("usb: renesas_usbhs: Add multiple clocks management")
