[linux-yocto] [PATCH 2/2] driver: usb: otg: fix build warning

[Meng.Li at windriver.com]

From: Limeng <Meng.Li at windriver.com>

Fix in file dwc_otg_pcd_intr.c
It is not reasonable to set the size of an array with a variable.
So, instead of define array directly, use kmalloc() to apply
memory space, and free it with kfree().

Fix in file dwc_otg_hcd_linux.c
Use the correct format string to output warning information.
