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 --- drivers/isdn/hisax/st5481_usb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/isdn/hisax/st5481_usb.c b/drivers/isdn/hisax/st5481_usb.c index ead0a4f..a0fdbc0 100644 --- a/drivers/isdn/hisax/st5481_usb.c +++ b/drivers/isdn/hisax/st5481_usb.c @@ -267,8 +267,8 @@ int st5481_setup_usb(struct st5481_adapter *adapter) } // The descriptor is wrong for some early samples of the ST5481 chip - altsetting->endpoint[3].desc.wMaxPacketSize = __constant_cpu_to_le16(32); - altsetting->endpoint[4].desc.wMaxPacketSize = __constant_cpu_to_le16(32); + altsetting->endpoint[3].desc.wMaxPacketSize = cpu_to_le16(32); + altsetting->endpoint[4].desc.wMaxPacketSize = cpu_to_le16(32); // Use alternative setting 3 on interface 0 to have 2B+D if ((status = usb_set_interface(dev, 0, 3)) < 0) { -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
