Date: Wed, 19 Aug 2015 11:01:22 +0530 From: Vaishali Thakkar <vthakkar1994@...il.com> To: Felipe Balbi <balbi@...com> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] usb: gadget: f_uac1: 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@...il.com> --- drivers/usb/gadget/function/f_uac1.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/usb/gadget/function/f_uac1.c b/drivers/usb/gadget/function/f_uac1.c index 7856b33..5aa8d8a 100644 --- a/drivers/usb/gadget/function/f_uac1.c +++ b/drivers/usb/gadget/function/f_uac1.c @@ -57,8 +57,8 @@ static struct uac1_ac_header_descriptor_1 ac_header_desc = { .bLength = UAC_DT_AC_HEADER_LENGTH, .bDescriptorType = USB_DT_CS_INTERFACE, .bDescriptorSubtype = UAC_HEADER, - .bcdADC = __constant_cpu_to_le16(0x0100), - .wTotalLength = __constant_cpu_to_le16(UAC_DT_TOTAL_LENGTH), + .bcdADC = cpu_to_le16(0x0100), + .wTotalLength = cpu_to_le16(UAC_DT_TOTAL_LENGTH), .bInCollection = F_AUDIO_NUM_INTERFACES, .baInterfaceNr = { /* Interface number of the first AudioStream interface */ @@ -186,7 +186,7 @@ static struct uac_iso_endpoint_descriptor as_iso_out_desc = { .bDescriptorSubtype = UAC_EP_GENERAL, .bmAttributes = 1, .bLockDelayUnits = 1, - .wLockDelay = __constant_cpu_to_le16(1), + .wLockDelay = cpu_to_le16(1), }; static struct usb_descriptor_header *f_audio_desc[] = { -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
