usb: gadget: do not use __constant_cpu_to_le16 (0c91ca47) · Commits · 戴 / test

A trivial patch. cpu_to_le16() is capable enough to detect __builtin_constant_p() and to use an appropriate compile time ___constant_swahbXX() function. So we can use cpu_to_le16() instead of __constant_cpu_to_le16(). Signed-off-by:
