Re: [PATCH v3 3/3] usb: renesas_usbhs: Add multiple clocks management

Hi Shimoda-san

R-Car Gen3 needs to enable clocks of both host and peripheral.
Since [eo]hci-platform disables the reset(s) when the drivers are
removed, renesas_usbhs driver doesn't work correctly. To fix this
issue, this patch adds multiple clocks management on this
renesas_usbhs driver.

+			clk_bulk_disable_unprepare(priv->num_clks, priv->clks);

I think clk_bulk_xxx() will do nothing if priv->num_clks was 0.
priv->num_clks check is not neede, I think.

Best regards
