usbip: vhci_hcd: Convert use of __constant_cpu_to_le16 to cpu_to_le16
In big endian cases, macro cpu_to_le16 unfolds to __swab16 which provides special case for constants. In little endian cases, __constant_cpu_to_le16 and cpu_to_le16 expand directly to the same expression. So, replace __constant_cpu_to_le16 with cpu_to_le16 with the goal of getting rid of the definition of __constant_cpu_to_le16 completely. The semantic patch that performs this transformation is as follows: @@expression x;@@ - __constant_cpu_to_le16(x) + cpu_to_le16(x) Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
