6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kaustabh Chakraborty <kauschluss@xxxxxxxxxxx>
commit e2158c953c973adb49383ddea2504faf08d375b7 upstream.
In exynos5_usbdrd_{pipe3,utmi}_set_refclk(), the masks
PHYCLKRST_MPLL_MULTIPLIER_MASK and PHYCLKRST_SSC_REFCLKSEL_MASK are not
inverted when applied to the register values. Fix it.
