Smatch reports the following error:

drivers/phy/qualcomm/phy-qcom-usb-hsic.c:82 qcom_usb_hsic_phy_power_on()
warn: 'uphy->cal_clk' from clk_prepare_enable() not released on lines:
58.
drivers/phy/qualcomm/phy-qcom-usb-hsic.c:82 qcom_usb_hsic_phy_power_on()
warn: 'uphy->cal_sleep_clk' from clk_prepare_enable() not released on
lines: 58.
drivers/phy/qualcomm/phy-qcom-usb-hsic.c:82 qcom_usb_hsic_phy_power_on()
warn: 'uphy->phy_clk' from clk_prepare_enable() not released on lines:
58.

Fix this by calling proper clk_disable_unprepare calls.
