usb: renesas_usbhs: fix __le16 warnings
Fix the warnings generated by casting to/from __le16 without using the correct functions. Fixes the following sparse warnings: drivers/usb/renesas_usbhs/common.c:165:25: warning: incorrect type in assignment (different base types) drivers/usb/renesas_usbhs/common.c:165:25: expected restricted __le16 [usertype] wValue drivers/usb/renesas_usbhs/common.c:165:25: got unsigned short drivers/usb/renesas_usbhs/common.c:166:25: warning: incorrect type in assignment (different base types) drivers/usb/renesas_usbhs/common.c:166:25: expected restricted __le16 [usertype] wIndex drivers/usb/renesas_usbhs/common.c:166:25: got unsigned short drivers/usb/renesas_usbhs/common.c:167:25: warning: incorrect type in assignment (different base types) drivers/usb/renesas_usbhs/common.c:167:25: expected restricted __le16 [usertype] wLength drivers/usb/renesas_usbhs/common.c:167:25: got unsigned short drivers/usb/renesas_usbhs/common.c:173:39: warning: incorrect type in argument 3 (different base types) drivers/usb/renesas_usbhs/common.c:173:39: expected unsigned short [usertype] data drivers/usb/renesas_usbhs/common.c:173:39: got restricted __le16 [usertype] wValue drivers/usb/renesas_usbhs/common.c:174:39: warning: incorrect type in argument 3 (different base types) drivers/usb/renesas_usbhs/common.c:174:39: expected unsigned short [usertype] data drivers/usb/renesas_usbhs/common.c:174:39: got restricted __le16 [usertype] wIndex drivers/usb/renesas_usbhs/common.c:175:39: warning: incorrect type in argument 3 (different base types) drivers/usb/renesas_usbhs/common.c:175:39: expected unsigned short [usertype] data Note.
