[PATCH 4.14 138/210] phy: qualcomm: call clk_disable_unprepare in the error handling

[Greg Kroah-Hartman]

From: Dongliang Mu <mudongliangabcd@xxxxxxxxx>

[ Upstream commit c3966ced8eb8dc53b6c8d7f97d32cc8a2107d83e ]

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.
